  1. http://javascript.about.com/library/blreserved.htm lists them quite nicely.

  2. 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.

  3. 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!
