Note The match () method retrieves the string Object to find one or more text that matches the regexp. The behavior of this method depends to a large extent on whether RegExp has a flag g. If RegExp does not have a flag G, then the match () method can only perform a match in Stringobject. If no matching text is found, match () returns NULL. Otherwise, it returns an array that holds information about the matching text it finds.
