HI
You can't use reserved words as variables or function names. You can
use them as object properties, but only if they're passed in as a
string (by wrapping them in quotation marks)
var o = {delete: true}; // causes an error because delete is a
reserved word.
o.delete; // same error as before.
var o = {"delete": true}; // fine.
o['delete']; // true
If you're looking for a full list of reserved words, try the page at
MDC: https://developer.mozilla.org/en/JavaScript/Reference/reserved_words
Hope that clears a few things up
