7. Array and Object Destructuring

Destructuring helps in avoiding the need for temp variables when dealing with object and arrays.

function foo() {
    return [1, 2, 3];
}
let arr = foo(); // [1,2,3]
let [a, b, c] = foo();
console.log(a, b, c); // 1 2 3
function bar() {
    return {
        x: 4,
        y: 5,
        z: 6
    };
}
let { x: a, y: b, z: c } = bar();
console.log(a, b, c); // 4 5 6
