Array Destructuring

var [name, age] = ["Hemant", 20, "Hyd"];

// using rest operator
var team = ["Hemant", "Vinay", "player1", "player2", "playesr3"]
var [ Boss, Superboss, ...Players ] = team;
console.log(Boss, Superboss, Players); // Hemant Vinay ["player1","player2","playesr3"]

Swap variable

var a =2, b=4;
[a, b] = [b, a];
console.log(a, b); // 4, 2
