We've replaced Michael's JavaScript interpreter with Cthulhu. Let's see if he can tell the difference!

fun_with_javascript.js

// Let's have some fun with JavaScript.

{} + 0
// => 0

// That's a little strange, but okay. Surely nothing would change if I wrapped
// the whole thing in parens, right?

({} + 0)
// => "[object Object]0"

// Okay, that's weird. Let's see if strict equality can tell the difference
// between the two.

{} + 0 === ({} + 0)
// => false

// Good, at least JavaScript isn't completely sadistic. Surely the result would
// be the same if I compared them in the opposite order...

({} + 0) === {} + 0
// => true

// Welcome to JavaScript; where a == b && b != a
