extend-arguments v0.9.2

extendArguments.js

Why?

Because I can. Just a proof of concept.

How to install?

npm install extend-arguments

How can I use this?

Basic usage

var extendArguments = require('extend-arguments');
extendArguments('foo', 'bar');

extendArguments('forEach', Array.prototype.forEach);
(function() {
    arguments.forEach(console.log.bind(console));
})('a','b', 'c')
// logs 'a', 'b', 'c'

({0: 1, length: 1}).forEach(console.log.bind(console));
// TypeError: (intermediate value).forEach is not a function

Object.prototype.forEach = function() {
    throw new Error('Just testing.');
}

({0: 1, length: 1}).forEach(console.log.bind(console)); // Error: Just testing

(function() {
    arguments.forEach(console.log.bind(console));
})('a','b', 'c') // logs 'a', 'b', 'c'

Extend by object

Extend by literal

extendArguments({
    forEach: Array.prototype.forEach,
    toArray: Array.prototype.slice
});

Extend by Array methods

var methodsFromArray = {};
Object.getOwnPropertyNames(Array.prototype).forEach(function(el) {
    methodsFromArray[el] = Array.prototype[el];
});

extendArguments(
    methodsFromArray
);

TODO:

ArgumentsPrototype object

ArgumentsPrototype.foo = 'bar';
(function() {
    return arguments.foo;
}); // bar
