JavaScript compares things weirdly

— SjG @ 2:52 pm

We’ve already established that PHP compares things weirdly.

It shouldn’t surprise us that JavaScript does too.

Consider the following:

> var k=['hello'];
undefined
> (k=='hello'?'Equals':'Nope');
Equals

Now, purists will point out that that’s an “equals” operator not an “identity” operator, but I mean seriously? We’re just going to pretend that


> ['hello']=='hello'
true

I think I’ll just go and rewrite all my client side code in C now.
