Question

What are enhanced object literals?

Answer 1

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}
