Answer 2

Answer:

There's no limit to the length of the variable name.

You can't use one of JavaScript's reserved words as a variable name. All programming languages have a supply of words that are used internally by the language and that can't be used for variable names because doing so would cause confusion (or worse). Note, too, that JavaScript also has many keywords that should be avoided as well.
