Why is camel case used for readyState but not for onreadystatechange?

They're both properties of the XHR object. What gives?

I have no idea...

However, this stranger on the internet says that events are usually lowercase, while other stuff isn't. Sounds roughly right to me :).

In this specific case, readyState is a property, but onreadystatechange is an event.

Cheers :beers:
