Coding Horror: Learn to Read the Source, Luke

The transformative power of "source always included" in JavaScript is a major reason why I coined – and continue to believe in – Atwood's Law. Even if "view source" isn't built in (but it totally should be), you should demand access to the underlying source code for your stack. No matter what the documentation says, the source code is the ultimate truth, the best and most definitive and up-to-date documentation you're likely to find. This will be true forever, so the sooner you come to terms with this, the better off you'll be as a software developer.
