JavaScript likes to be wacky, as in JavaScript it tries as hard as it possibly can for two things to be "==" so it doesn't have to return false. For example, in JavaScript, 0 is "==" to: false, 0, the empty string, "0", [], and [0]. It's important to know this behavior in JavaScript so you can know how to read JavaScript code, and also so you know that nine times out of ten it is better for your code to use "===" instead of "==".
