If you are seeking a front-end programmer's job and are unsure how to prepare for an interview, there is no need to worry. This article sheds light on all the complicated and confusing questions interviewers are likely to ask to give you a better picture of what employers want you to know. The article covers interview questions for both freshers and experienced individuals.

What is Front-End Development?

Front-end development refers to the realm of web development that concentrates on what users see on their end. It revolves around transforming the code created by backend developers into a graphical interface, ensuring that data is delivered in a simple, easy-to-read format. Without front-end development, all one can see on a website or web application would be some undecipherable codes. Frontend developers help people with no coding background understand and utilize web applications and websites. Web applications such as Canva, Facebook, and Google Apps are products of both front-end and back-end developers working together.

Apart from ensuring that users can understand and effectively use a web application's graphical interface, front-end developers have other responsibilities. For example, front-end developers must ensure that web applications or websites are functional across different devices. Note that systems differ in their operating system (OS) and screen size. A user can own a Windows tablet, a MacBook, and an Android mobile phone. Despite device type and OS, the responsibility of the front-end developer is to ensure the application or website works. It's important to note that users may prefer different web browsers; front-end developers must build a website carefully that functions seamlessly on Mozilla Firefox, Chrome, Safari, Microsoft Edge, Internet Explorer, and Opera.

Front-End Developer Interview Questions for Freshers

1. What skills does a front-end developer need?

HTML META TAGS

In HTML, meta tags are used to provide information about the web page. They are placed in the head section of HTML and are not actually visible to users. Some common meta tags include the description tag, which provides a brief summary of the page, and the keywords tag, which lists relevant keywords related to the page's content. Other meta tags may specify the character set used in the document or provide instructions to web crawlers. Proper use of meta tags can improve search engine optimization and help users find relevant content.

Difference Between DIV and SPAN

DIV: It is a block-level element that is used to group larger sections of HTML elements and apply CSS styles to them. In other words, DIV can be used to divide the webpage into logical sections and apply different styles to each of them.

SPAN: It is an inline-level element that is used to group small chunks of HTML elements and apply CSS styles to them. In other words, SPAN can be used to apply styles to specific parts of the text, such as individual words or letters.

In summary, DIV is used to group larger sections of HTML elements, while SPAN is used to group smaller chunks of HTML elements.

What is React JS?

React JS, also known as React, is a popular open-source JavaScript library used for building user interfaces. It was created by Facebook, and it allows developers to create reusable UI components and manage the app's state efficiently.

React follows a declarative paradigm, where developers describe the desired outcome, and React takes care of the underlying operations to achieve that outcome. Its virtual DOM (Document Object Model) implementation allows for efficient rendering and updating of components, improving the app's overall performance.

React has gained popularity in the industry for its ease of use, flexibility, and large supportive community. It is often used in conjunction with other popular libraries, such as Redux and React Router, to create powerful and scalable web applications.

// Example of a React component
import React from 'react';

const MyComponent = () => {
  const [count, setCount] = React.useState(0);
  
  const handleClick = () => {
    setCount(count + 1);
  }
  
  return (
    <div>
      <h1>My Component</h1>
      <p>Count: {count}</p>
      <button onClick={handleClick}>Click me</button>
    </div>
  );
}

Advantages of REST Web Services

There are several advantages of using REST web services:

1. Scalability: REST web services use HTTP protocol which is considered scalable. This makes it easier to handle large amounts of requests and data.
2. Flexibility: REST web services support multiple data formats such as XML, JSON and plain text. This makes it easier for clients to communicate with the server.
3. Easy to implement: REST web services are relatively easy to implement compared to other web services such as SOAP. It does not require as much code or special libraries.
4. Stateless: REST web services are stateless which means that the server does not retain any information about the client. This makes it easier to load balance multiple requests across multiple servers.
5. Cacheable: REST web services can be cached which can reduce server load and improve performance.

In summary, REST web services are a simple, scalable and flexible way to communicate between clients and servers over the internet.

// Example GET request using REST web service
GET /api/products/123
Host: www.example.com
Accept: application/json

How Browsers Render the User Interface?

// Here is a basic summary of the UI rendering process in web browsers:

1. HTML is received by the browser and is parsed to construct the DOM (Document Object Model).
2. CSS (Cascading Style Sheets) is received and parsed to construct the CSSOM (CSS Object Model).
3. The DOM and CSSOM are combined to generate the render tree, which is a tree of all visual elements to be displayed on the page.
4. The layout process takes place, where the size and position of each element are calculated.
5. Finally, each element is painted onto the screen.

// To optimize the UI rendering process, developers can:

- Use CSS efficiently to minimize the amount of rendering required by the browser.
- Remove any unnecessary DOM elements that are not being used on the page.
- Use JavaScript carefully since it can manipulate the DOM and trigger rendering of the UI.
- Minimize or remove any inline styles on elements to reduce the amount of CSS parsing required.

Understanding Grid Systems in CSS

In web design, a grid system is a structure that allows content to be organized and presented in an aesthetically pleasing and organized manner. CSS provides developers with the ability to create grid systems that define rows and columns, specify the size of each element, and determine how elements are positioned in the grid layout. This can be achieved through the use of CSS frameworks such as Bootstrap, Foundation, and Materialize, or by custom coding a grid system using CSS properties such as display, grid-template-rows, grid-template-columns, and grid-gap. Grid systems are instrumental in creating responsive web designs that look great on a variety of devices and screen sizes.

Distinction between Class and Prototypal Inheritance in JavaScript

JavaScript supports both class and prototypal inheritance. However, there are some distinguishing factors between the two.

Class Inheritance: Class inheritance in JavaScript is based on classes. A class defines the behavior of an object and includes properties and methods. The class is used to create objects that inherit the same properties and methods. In class inheritance, a parent class is defined and child classes are created that inherit the properties and methods of the parent class.

Prototypal Inheritance: Prototypal inheritance in JavaScript is based on prototypes. In this type of inheritance, the object inherits from its prototype. The prototype is an object that defines the behavior of the object. If a property or method is not found on the object, it looks for it on the prototype. If it is not found on the prototype, it looks for it on the prototype's prototype and so on until it reaches the end of the prototype chain.

In summary, class inheritance is based on defining a parent class, and creating child classes that inherit from it, while prototypal inheritance is based on objects inheriting from their prototypes.

Explanation of User-Centered Design

User-centered design is an approach that focuses on designing products, services or systems based on the needs, goals, and behavior of the end-users. It involves understanding user needs, preferences and behaviors through research, and involving them throughout the design process to ensure that the end product meets their requirements.

The user-centered design process involves several stages such as research, design, and testing. In the research phase, designers conduct various methods such as surveys, interviews, and usability testing to get a better understanding of their users. This information is then used to create design concepts that take into account the user's behavior, motivation, and preferences.

In the design phase, designers create prototypes of the proposed product or service using wireframes, sketches, or visual designs. These prototypes are tested with users in the testing phase to get feedback on the user experience and make necessary modifications to the design.

The ultimate goal of user-centered design is to create products or services that are easy to use, effective, and enjoyable for the users. By putting users at the center of the design process, designers can create solutions that meet the needs of their target audience and provide a better user experience.

What is Clickjacking?

Clickjacking is a malicious technique used by attackers to trick users into clicking on a button or link on a web page that is disguised as something else. This is typically done by presenting a transparent or opaque layer over the legitimate button or link. When the user clicks on the disguised button or link, they unknowingly perform an action that could harm their computer or compromise their personal information.

// Example of clickjacking code
<style>
    #malicious-button {
        position: absolute;
        top: 0;
        left: 0;
        width: 100%;
        height: 100%;
        opacity: 0;
        z-index: 999;
    }
</style>
<iframe src="https://legitimate-website.com" width="100%" height="100%" frameborder="0"></iframe>
<button id="malicious-button">Click me</button>

When and Why to Use Webpack?

Webpack is a powerful tool commonly used in web development, especially for projects that are larger and more complex in nature. Here are some situations when and why to use Webpack:

1. Bundling: When your project has multiple JavaScript files, CSS files, and other assets, Webpack can bundle them all into a single file. This improves performance by reducing the number of requests made to the server by your application.

2. Transpiling: If you are using new JavaScript features that aren't supported by all browsers yet, Webpack can transpile your code into a version that is readable by all browsers.

3. Minification: Webpack can also minimize the size of your assets by removing unnecessary characters and code, which can further improve performance.

4. Hot Module Replacement: With Webpack, you can make live updates to modules without having to refresh the entire page. This feature saves time and makes development more efficient.

In summary, Webpack is a great tool to use when you have a large, complex project with multiple assets that need to be bundled, transpiled, and customized for optimal performance.

Three Methods to Decrease Page Load Time

There are several ways to decrease page load time, three of which are:

1. Minimizing HTTP requests: This involves reducing the number of HTTP requests made by the browser when loading a web page. You can achieve this by minimizing the use of images, scripts, and stylesheets.

2. Compressing files: By compressing files such as images and scripts, you can significantly reduce their size, which in turn decreases the overall page load time.

3. Enabling caching: Caching involves storing frequently accessed content on the user's device so that it doesn't have to be reloaded each time the user visits the page. This significantly reduces the amount of time it takes to load the page on subsequent visits.

How does the server handle pages with content in multiple languages?

When handling pages with content in multiple languages, the server typically uses a combination of HTML markup and HTTP headers to indicate which language(s) are being used on the page. The HTML markup can include language-specific attributes such as "lang" and "hreflang", while the HTTP headers can include the "Content-Language" and "Vary" headers to indicate the language(s) of the content and that the language may vary based on user preferences, respectively. Additionally, the server may use language detection techniques to automatically determine the language of the content based on the user's browser settings or other factors.

Explanation of why the data attribute was used in HTML and why it is no longer recommended.

The data attribute was utilized in HTML to store additional information about an HTML element that was not directly related to its appearance or functionality. This data could be used by JavaScript or CSS to enhance the behavior of the element or customize its styling.

However, the use of data attributes to store data is no longer recommended because it can cause issues with accessibility, search engine optimization, and maintainability of the code. Additionally, with the advent of new technologies like custom elements and web components, there are now better ways to encapsulate data and behavior within HTML elements. Thus, it is advisable to use alternative methods like data models or APIs to manage data.

Benefits of CoffeeScript over JavaScript

CoffeeScript is a programming language that compiles to JavaScript and provides a number of benefits over JavaScript:

• Simplicity: CoffeeScript has a simpler syntax than JavaScript, making it easier to write and understand.
• Readability: CoffeeScript's syntax is more readable than JavaScript and makes it easier to maintain code.
• Less Code: CoffeeScript allows developers to express the same logic with fewer lines of code than JavaScript. This means less code to write, read, and maintain.
• Eliminates Common Errors: CoffeeScript eliminates many of the common errors that JavaScript developers face due to JavaScript's loose typing and rules.
• Better Features: CoffeeScript provides better features such as comprehensions, destructuring, and the existential operator, making it easier to write code more elegantly and concisely.
• Compatibility: CoffeeScript is fully compatible with JavaScript, which means it can be integrated into any JavaScript project without issue.

// Example code in CoffeeScript
square = (x) -> x * x

// The same code in JavaScript
var square = function(x) {
  return x * x;
};

Interview Question for Experienced Front-End Developers

JSON.stringify()

is a built-in function in JavaScript that converts a JavaScript object into a JSON string. This is useful when sending data from a client-side application to a server or storing data in a database. The syntax for using

JSON.stringify()

is:

JSON.stringify(object)

The

object

parameter is the JavaScript object to be converted to a JSON string. The resulting JSON string can then be sent to a server or stored in a database as a string value. It's worth noting that

JSON.stringify()

can also take two additional parameters,

replacer

and

space

, which can be used to customize the JSON output.

Elements of the CSS Box Model

The CSS Box Model consists of the following elements:

• Content: This is where the website's text, images, and media are displayed.
• Padding: This is the space between the content and the border.
• Border: This is the line that surrounds the padding and content.
• Margin: This is the space between the border and the surrounding elements.

In CSS, each of these elements can be styled separately to achieve the desired layout and design of the website. Understanding the CSS Box Model is essential for creating visually appealing websites.

What is Progressive Rendering?

Progressive rendering is a technique used in web development to improve the loading speed of web pages by displaying content incrementally instead of waiting for the entire page to load before showing anything. With progressive rendering, the browser starts rendering parts of the page as they become available, which helps users see something on the page while other components continue to load in the background.

Progressive rendering is particularly important when it comes to mobile devices, which may have slower network connections. By using progressive rendering, developers can improve the user experience by allowing users to access content more quickly and making pages feel more responsive.

// Example of progressive rendering using lazy loading
const images = document.querySelectorAll('img[data-src]');

function preloadImage(img) {
  const src = img.getAttribute('data-src');
  if (!src) {
    return;
  }

  img.src = src;
}

const imageOptions = {
  threshold: 0,
  rootMargin: '0px 0px 100px 0px'
};

const imageObserver = new IntersectionObserver((entries, imageObserver) => {
  entries.forEach(entry => {
    if (!entry.isIntersecting) {
      return;
    } else {
      preloadImage(entry.target);
      imageObserver.unobserve(entry.target);
    }
  })
}, imageOptions);

images.forEach(image => {
  imageObserver.observe(image);
});

Benefits of using the srcset attribute in an image tag

The srcset attribute in an image tag provides the benefit of serving different image sizes to different devices based on their screen resolution and pixel density. This allows for faster loading times and a better user experience as smaller devices can load smaller images while larger devices can load higher resolution images. Additionally, using srcset can help save bandwidth and reduce server load by only loading the necessary image size for each device.

Difference Between MySQL and MongoDB

MySQL and MongoDB are both popular database management systems, but they have some key differences.

MySQL is a relational database management system that stores data in tables with defined relationships between them. It requires a structured schema and follows ACID (Atomicity, Consistency, Isolation, Durability) properties. It is suitable for applications that have structured data and require complex transactions.

On the other hand, MongoDB is a NoSQL document-oriented database management system that stores data as documents in collections without predefined schema. It follows BASE (Basically Available, Soft state, Eventually Consistent) properties. MongoDB is suitable for applications that require high scalability, flexibility, and fast read-write operations, particularly when dealing with unstructured data.

In summary, MySQL is best suited for applications that need a structured data schema, whereas MongoDB is a good choice for applications that require high scalability, flexibility, and speed in dealing with unstructured data.

Defining Anonymous Functions in JavaScript

In JavaScript, an anonymous function is a function that has no name identifier and can be defined without being assigned to a variable. Here is an example of how to define an anonymous function:

// Anonymous function that takes two arguments and returns their sum
var sum = function(a, b) {
  return a + b;
};

// Calling the anonymous function
sum(2, 3); // Returns 5

In this example, we have defined an anonymous function that takes two arguments, `a` and `b`, and returns their sum. The function is assigned to the variable `sum`, which can be used to call the function later on.

Anonymous functions are useful in situations where a function may only be needed once, or where a function needs to be passed as an argument to another function. They are often used in event handlers and callbacks.

It's important to note that not all anonymous functions are created equal. Some can be created using an arrow function syntax like this:

// Anonymous function using arrow function syntax
var sum = (a, b) => {
  return a + b;
};

Arrow functions have a shorter syntax and automatically bind `this` to the parent context. However, they are not supported in some older browsers, so it's important to be aware of the limitations of using arrow functions.

Understanding CSS Image Sprites and Their Use

CSS image sprites refer to a technique where multiple images are combined into one image, and then positioned using CSS background-image and background-position properties. Image sprites are primarily used to reduce the number of HTTP requests and load time for web pages. By combining images into a single file, the browser needs to download only one image instead of multiple images, making a website faster and more efficient. Additionally, by positioning the image using CSS, it becomes easier to display specific portions of the image without downloading the entire file. This technique is commonly utilized for icons, buttons, and other graphical elements.

Some Suggestions for Fixing Browser-Specific Styling Issues:

1. Use a CSS Reset or Normalize.css to level the playing field for different browsers.

2. Write browser-specific CSS code by identifying the browser and writing specific rules for the problematic browser.

3. Use CSS hacks or workarounds to target specific browsers. However, use them sparingly and with caution.

4. Use a CSS Preprocessor like Sass or Less to write browser-specific code in a more organized and streamlined way.

5. Test your website thoroughly on different browsers and devices to identify and fix any styling issues.

Pitfalls of Using a CSS Preprocessor like Sass

Using a CSS preprocessor like Sass can bring a lot of benefits to your CSS workflow, but there are also some pitfalls to watch out for. Some potential issues to keep in mind include:

1. Steep learning curve: Sass has its own syntax that can take some time to learn, especially if you're not already comfortable with programming concepts like variables and functions.

2. Debugging can be tricky: Because Sass compiles to regular CSS, you may run into issues where your Sass code compiles incorrectly, making it harder to debug errors.

3. Overcomplication: It's easy to get carried away with Sass features like nesting and mixins, which can lead to overly complex code that's hard to maintain.

4. Dependency on tools: Using Sass requires a build process or task runner like Grunt or Gulp, which adds an extra layer of complexity to your development setup.

5. File organization: Because Sass allows for partials and importing, it's important to have a clear organization system in place for your files to avoid confusion and ensure consistency.

Overall, Sass can greatly improve your CSS workflow, but it's important to weigh the benefits against the potential pitfalls before deciding whether to adopt it in your projects.

Ways to Optimize Front-End Pages

There are several ways to optimize a front-end page:

1. Minimize HTTP Requests:

Reduce the number of HTTP requests being made by combining multiple stylesheets and scripts to minimize requests.

2. Compress and Optimize Images:

Compress and optimize images to reduce their file size without affecting their quality. This can significantly improve the page load time.

3. Use Caching:

Enable browser caching to store frequently accessed files in the user's cache memory. This will speed up the site's load time when revisited.

4. Minimize HTML, CSS, and JavaScript:

Minify HTML, CSS, and JavaScript files to reduce their size and remove unnecessary comments and whitespace. This will improve page load times.

5. Use a Content Delivery Network (CDN):

CDNs distribute a site's content across multiple servers around the world, reducing the load time for users accessing the site from different locations.

6. Optimize CSS and JavaScript:

Remove unused CSS and JavaScript code. This will reduce the size of these files, making them easier to download and reducing page load times.

By implementing these optimization techniques, your front-end page performance will improve, providing a better user experience for your visitors.

Difference between Attribute and Property in Web Development

In web development, attributes and properties are both used to describe characteristics of HTML elements. However, there is a difference between the two.

Attributes are defined in HTML and provide initial values for an element. They are typically static and do not change unless explicitly modified by script or user interaction. Examples of attributes include "id", "class", and "src".

On the other hand, properties are accessed and manipulated via JavaScript. They provide the current value of an element and can change dynamically during runtime. Examples of properties include "innerHTML", "style", and "className".

It is important to note that not all attributes have corresponding properties and vice versa. Additionally, some properties are read-only and cannot be set using JavaScript.

In summary, attributes are defined in HTML and provide initial values, while properties are accessed and modified via JavaScript and provide the current value.

Difference between == and === in JavaScript

In JavaScript, both '==' and '===' are used for equality comparison but they differ in their behavior:

'==' performs type coercion, i.e it converts the operands to a common type before comparing them. This means that '5' == 5 would be true, as the string '5' is converted to a number before comparison.

'===' performs a strict comparison without type coercion. This means that '5' === 5 would be false, as the string '5' is not the same as the number 5 when their types are compared.

It is generally recommended to use '===' over '==' to avoid unexpected behavior due to type coercion.

Why do we use the "use strict" statement in JavaScript?

In JavaScript, the "use strict" statement is used to activate the strict mode for code. The strict mode enforces certain rules in code that help prevent common mistakes and make code more secure.

Some examples of the rules enforced in strict mode include: - Variables must be declared before they are used - Function parameters cannot have the same name - Assigning a value to a read-only property or variable will result in an error - Deleting a variable or function that is not deletable will result in an error

By using the "use strict" statement, we can catch errors and potential bugs earlier in the development process, which can save time and effort in the long run. Additionally, strict mode can help make code more optimized and reliable.

Major HTTP Requests

HTTP (Hypertext Transfer Protocol) requests are used for communication between a client and server over the internet. There are several types of HTTP requests, including:

- GET: is used to retrieve data from a server using a specific URI (Uniform Resource Identifier). - POST: is used to submit data to a server to be processed. - PUT: is used to update an existing resource on the server. - DELETE: is used to delete a resource from the server. - HEAD: is used to retrieve metadata from the server without requesting the actual data. - OPTIONS: is used to determine the server's available communication options for a specific resource. - PATCH: is used to partially update a resource on the server. - CONNECT: is used to establish a network connection to a server. - TRACE: is used to retrieve a diagnostic trace of the actions taken by a server to handle a specific request.

Understanding these HTTP requests can help developers build efficient, secure, and reliable web applications.
