javascript function declaration

//Function declarations load 
//before any code is executed
//while 
//Function expressions load
//only when the interpreter reaches that line of code.
//eg. 
add(1,2); 
function add(a,b){	//this is a function declaration 
  return a+b;
}
sum(1,5); //this is a function expression will throw initialization error
const sum = () => a+b; //function expression is strored in variable

                                    //1st (simple function)
function hello1() {
    return &quot;Hello simple function&quot;;
}

//2nd (functino expression)
hello2 = function() {
    return &quot;Hello functino expression&quot;;
}

// 3rd ( IMMEDIATELY INVOKED FUNCTION EXPRESSIONS (llFE))
hello3 = (function() {
    return &quot;Hello IMMEDIATELY INVOKED FUNCTION EXPRESSIONS (llFE)&quot;;
}())

//4th (arrow function)
hello4 = (name) =&gt; { return (&quot;Hello &quot; + name); }
    //OR
hello5 = (name) =&gt; { return (`Hello new ${name}`) }

document.getElementById(&quot;arrow&quot;).innerHTML = hello4(&quot;arrow function&quot;);

document.write(&quot;&lt;br&gt;&quot; + hello5(&quot;arrow function&quot;));
