How to bind function arguments without binding this?

Question

In Javascript, how can I bind arguments to a function without binding the this parameter?

For example:

//Example function.
var c = funct         


        

Answer 1

In the native bind method the this value in the result function is lost. However, you can easily recode the common shim not to use an argument for the context:

Function.prototype.arg = function() {
    if (typeof this !== "function")
        throw new TypeError("Function.prototype.arg needs to be called on a function");
    var slice = Array.prototype.slice,
        args = slice.call(arguments), 
        fn = this, 
        partial = function() {
            return fn.apply(this, args.concat(slice.call(arguments)));
//                          ^^^^
        };
    partial.prototype = Object.create(this.prototype);
    return partial;
};
