Reserved Keywords in Javascript

What Javascript keywords (function names, variables, etc) are reserved?

  1. We should be linking to the actual sources of info, rather than just the top google hit.

    JSscript 8.0:

    I'll look for ECMAScript links later.

  2. lists them quite nicely.

  3. This is one of the many things discussed in "JavaScript: The Good Parts" by Douglas Crockford.

    By the way, I'm not affiliated with the publisher; The book is just that awesome.

  4. I discovered today that the word "keywords" is a reserved word in IE javascript. It turns out to be an object that contains a list of all the keywords. No errors are generated if you try and use this as a variable, but any time you try and access the value of your variable you get an object back instead of what you assigned to it. Arg!

  5. header and footer just broke my script in IE8.
