es6 assign variables from object code example
Example 1: array destructuring
//Without destructuring
const myArray = ["a", "b", "c"];
const x = myArray[0];
const y = myArray[1];
console.log(x, y); // "a" "b"
//With destructuring
const myArray = ["a", "b", "c"];
const [x, y] = myArray; // That's it !
console.log(x, y); // "a" "b"
Example 2: javascript destructing
/*
* On the left-hand side, you decide which values to unpack from the right-hand
* side source variable.
*
* This was introduced in ES6
*/
const x = [1, 2, 3, 4, 5]
const [a, b] = x
console.log(a) // prints out: 1
console.log(b) // prints out: 2
