Javascript's 'bind' re-implemented.

gistfile1.txt

var bind = function(fn, context) {
  var args = Array.prototype.slice.call(arguments, 2);
  
  return function() {
    return fn.apply(context, args.concat(Array.prototype.slice.call(arguments)));
  };
};

var args = [].slice.call(arguments, 2); // Line 2 error, Array object can be overwritten

Line 2: better Apply an Array :)

Mine :)

Function.prototype.bind = function (scope) {
  var args = [].slice.call(arguments, 1),
      fn = this;

  return function () {
    fn.apply(scope, args.concat([].slice.call(arguments)));
  };
};
