Regular expressions

Learn them. They look scary but once you get used to them they're a godsend.

This one makes sure a string begins with "message" and is followed by a number:

Code:

/^message[0-9]*$/

Looks complex but it means "if the string has nothing but beginning with "message" and then followed by any number of digits and that's it".
