tp-hk / immutability-vs-reassignment.js

Created October 17, 2018 21:28 — forked from battmanz/immutability-vs-reassignment.js

Demonstrates the difference between an immutable object and a variable that cannot be reassigned

	'use strict';

	// CASE 1: The object is mutable and the variable can be reassigned.
	let o1 = { foo: 'bar' };

	// Mutate the object
	o1.foo = 'something different';

	// Reassign the variable
	o1 = { message: "I'm a completely new object" };
