Is there a splice method for strings?

Question

The Javascript splice only works with arrays. Is there similar method for strings? Or should I create my own custom function?

The substr(),

Answer 1

Here's a nice little Curry which lends better readability (IMHO):

The second function's signature is identical to the Array.prototype.splice method.

function mutate(s) {
    return function splice() {
        var a = s.split('');
        Array.prototype.splice.apply(a, arguments);
        return a.join('');
    };
}

mutate('101')(1, 1, '1');

I know there's already an accepted answer, but hope this is useful.
