What are enhanced object literals

Object literals make it easy to quickly create objects with properties inside the curly braces. For example, it provides shorter syntax for common object property definition as below.

//ES6
var x = 10,
y = 20;
obj = { x, y };
console.log(obj); // {x: 10, y:20}
//ES5
var x = 10,
y = 20;
obj = { x: x, y: y };
console.log(obj); // {x: 10, y:20}
