Objects

Object Property Shorthand

If you want to define a property in an object, and that key name already exists as a variable within the object’s scope, you don’t have to explicitly assign a value. You can use just the key name, and that variable’s value is used automatically.

// Some details
let name = 'Merlin';
let job = 'wizard';
let age = 'old AF';

// The object
let wizard = {
	name: name, // The old way
	job,        // ES6 shorthand
	age         // ES6 shorthand
};
