playing with bind, call and apply

gistfile1.js

var foo = function () {
  console.log(this);
  console.log(arguments);
}

var context = {};

// shortcut with predefined context and arguments
var bar = Function.prototype.call.bind(foo, context, 'arg1', 'arg2');
bar('arg3'); // context, ["arg1", "arg2", "arg3"]

// shortcut without arguments and context
var bar = Function.prototype.call.bind(foo);
bar(context, 'arg1', 'arg1', 'arg2') // context, ["arg1", "arg2", "arg3"]

// shortcut with current context
var bar = Function.prototype.call.bind(foo, undefined);
bar('arg1', 'arg2', 'arg3') // Window, ["arg1", "arg2", "arg3"]


// functional approach to bind, call and apply
var bind = Function.prototype.call.bind(Function.prototype.bind);
var call = bind(Function.prototype.call, Function.prototype.call);
var apply = bind(Function.prototype.call, Function.prototype.apply);
