If you’re a novice like me I hope you can gain something from my ramblings.

Most modern programming languages have support for regex (regular expressions) but I’ll be focusing on Java Script’s implementation because that’s what I’m best at!

It can be reduced to a specific set of countries only but that wouldn't be an option for a worldwide international solution.

One part of me was curious about how all this phone matching machinery worked, and another part of me was curious if there's a way to reduce those 220 Kilo Bytes to something more reasonable while also getting rid of the library and rewriting it all in pure javascript.

Regular Expressions offer a concise and powerful search-and-replace mechanism.

They are patterns of characters used to perform search, extract or replace operations on the given text.

Sun added support for regular expression in Java 1.4 by introducing regex package.It doesn’t really matter though because the typical regex notation varies little between implementations (As far as I know).
