Reserved words in Javascript
The reserved words in this list have special meaning within Javascript so cannot be used as JavaScript variables, functions, methods, or object names. Some of these reserved words are currently used in JavaScript; others are reserved for future use.
Naming a variable var is probably the most common mistake. If you really are stuck for a meaningful variable name, call it myVar.
