define methods of objects in javascript
objectName.methodname = functionName;
var myObj = {
myMethod: function(params) {
// ...do something
}
// OR THIS WORKS TOO
myOtherMethod(params) {
// ...do something else
}
};

/// OBJECTS IN JAVASCRIPT
const testScore = {
damon: 89,
shawn: 91,
keenan: 80,
kim: 89,
};
Object.keys(testScore); // gives all keys
Object.values(testScore); // gives all values
Object.entries(testScore); // gives nested arrays of key-value pairs
// YOU CAN USE ( FOR-IN ) LOOP FOR ITERATION OVER OBJECTS
for (let person in testScore) {...}
// WE CAN'T DIRECTLY USE ( FOR-OF ) LOOP IN OBJECTS BUT WE CAN DO Like THIS:
for(let score of Object.values(testScore)){
console.log(score) // 89 91 80 89
}
Thank you!
