@Fabián: because it would be awfully slow. Regular Expressions are heavy-duty jobs and take lots of time and computing power – Javascript is no exception to this. And, the use of RegExp would grant us no benefit here compared to String.substr().

Why not just using:

function endsWith(string, suffix) { return new RegExp(suffix+”$”).test(string); }

and:

function startsWith(string, prefix) { return new RegExp(“^”+prefix).test(string); }

to test if a string ends or begins with a certain other string?

You can then, of course, use that method to augment the String prototype too:

String.prototype.beginsWith = function(term){
return dojo.string.beginsWith(this, term);
}

fun.
