The String type has several methods to do pattern-match.
match() method is essentially the same as calling a RegExp object's exec() method.
The match() method accepts a single argument, which is either a regular-expression string or a RegExp object.
var text = "cat, bat, sat, fat"; var pattern = /.at/; //same as pattern.exec(text) var matches = text.match(pattern); console.log(matches.index); //0 console.log(matches); //"cat" console.log(pattern.lastIndex); //0
The array returned from match() is the same array returned from RegExp's exec() method:
search() accepts a regular expression specified by either a string or a RegExp object.
search() method returns the index of the first pattern occurrence in the string or -1 if it's not found.
search() begins looking for the pattern at the beginning of the string.
var text = "cat, bat, sat, fat"; var pos = text.search(/at/); console.log(pos); //1
Here, search(/at/) returns 1, which is the first position of "at" in the string.
