Javascript Reference - JavaScript String match() Method

match() is the same as RegExp object's exec() method. The match() method accepts a regular-expression string or a RegExp object.

The first item of the returning array is the string that matches the entire pattern. Each other item of the returning array represents capturing groups in the expression.

This method returns null if no match is found.
