RegExp

Regular Expressions

Regular expressions are a way to describe patterns in string data. They form a small, separate language that is part of JavaScript and many other languages and tools.

In JavaScript, regular expressions are also objects (of type RegExp).

RegExp patterns are used with the exec and test methods, and with the match, replace, search, and split methods of String.
