Getting an error with Console.log('\x') in JavaScript

the problem occurs only when the word after the '\' begin with 'x'. I would like to know if \x is reserved word.

Backslash is used to escape characters. If you need a literal backslash, use \\.

It is not a reserved word, it's a way to print a character by its code:

>>> console.log('\x56');
V

In fact, Firebug tells you what's wrong if you omit the number:

SyntaxError: malformed hexadecimal character escape sequence

Like in many C-style languages, backslashes denote "escape sequences". More can be found here.
