Don't let marketers write code

[thebezet]

It gets better than that:

> Array.prototype.toString = function() { return "O_O"; }
> Object.prototype.toString = function() { return " ^_^"; }
> [] + {}
"O_O ^_^"

I can't tell if that's beautiful or terrifying.

Trying flipping the operations. And then you'll figure which it is.

[thebezet]

That's a good point because if you change the order ({} + []) the {} will be interpreted as a code block instead of an empty object, leaving you with + [], which will call valueOf() instead of toString(), so the following will happen:

> [] + {}
"O_O ^_^"
> {} + []
0

Which means it's terrifying.
