What is destructuring assignment and its uses?

Question

I have been reading about Destructuring assignment introduced in ES6.

What is the purpose of this syntax, why was it introduced, and what are some examples of how it

Answer 1

It is something like what you have can be extracted with the same variable name

The destructuring assignment is a JavaScript expression that makes it possible to unpack values from arrays or properties from objects into distinct variables. Let's get the month values from an array using destructuring assignment

var [one, two, three] = ['orange', 'mango', 'banana'];

console.log(one); // "orange"
console.log(two); // "mango"
console.log(three); // "banana"

and you can get user properties of an object using destructuring assignment,

var {name, age} = {name: 'John', age: 32};

console.log(name); // John
console.log(age); // 32
