Alex Sexton’s Explanation on Prototypal Inheritance in JavaScript

var defaults = { zero: 0, one: 1 }; var myOptions = Object.create(defaults); var yourOptions = Object.create(defaults); // When I want to change *just* my options myOptions.zero = 1000; // When you wanna change yours yourOptions.one = 42; // When we wanna change the **defaults** even after we’ve got our options // even **AFTER** we’ve already created our instances defaults.two = 2; myOptions.two; // 2 yourOptions.two; // 2
