cut out part of a string

Question

Say, I have a string

\"hello is it me you\'re looking for\"

I want to cut part of this string out and return the new string, something like

Answer 1

s = string.cut(5,7);

I'd prefer to do it as a separate function, but if you really want to be able to call it directly on a String from the prototype:

String.prototype.cut= function(i0, i1) {
    return this.substring(0, i0)+this.substring(i1);
}
