Enhanced Object Properties

ECMAScript 6 added several enhancements to object literals as part of the ES6 syntactic sugar. ES6 added three ways to simplify the creation of object literals. These simplifications include a more concise syntax for initializing object properties from variables, a more concise syntax for defining function methods, and computed object property names.

Note

Syntactic sugar is a syntax that is designed to make expressions easier to read and express. It makes the syntax "sweeter" because code can be expressed concisely.

Object Properties

The shorthand for initializing object properties allows you to make more concise objects. In ES5, we needed to define the object properties with a key name and a value, as shown in the following code:

function getPersionES5( name, age, height ) {
  return {
    name: name,
    age: age,
    height: height
  };
