JavaScript has powerful regular expression support.
A certain number of string functions can take arguments that are regular expressions to perform their work. These regular expressions can either be entered in literal format or as a call to the constructor of a RegExp object.
"aaewewedsdewddsxac".replace(new RegExp("[Aa]{2,}"), "b");
