1. ES6 .includes()
:
var S = "fullweb";
S.includes("web");
2. RegExp .search()
:
var S = "fullweb";
S.search(/web/);
3. RegExp .match()
:
var S = "fullweb";
S.match(/web/);
4. RegExp .test()
:
var S = "fullweb";
S.test(/web/);
5. Good old’ .indexOf()
:
var S = "fullweb";
S.indexOf("web");
I’ve tested them for speed in Chrome on a MacBook Pro, and it appears ES6 .includes()
is the fastest, and .match()
is the slowest, with all the others almost as fast as ES6 .includes()
.
