Bit better performance as starts and endWith

Alright I removed the startsWith and endsWith usage
String.prototype.substr() is deprecated (see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/substr) so we replace it with similar functions which aren't deprecated. Signed-off-by: Tobias Speicher <rootcommander@gmail.com>

String.prototype.substr() is deprecated so we replace it with functions which work similarily but aren't deprecated.
.substr() probably isn't going away anytime soon but the change is trivial so it doesn't hurt to do it.
