darsain / constructor-apply

Apply an arguments array to object constructor.

constructor-apply

Applies an array of arguments to an object constructor, ensuring the constructor is called with a new keyword.

Because you can't do:

var foo = new Foo.apply(ohLordWhatDoIPassHere, arguments);

Install

With component(1):

component install darsain/constructor-apply

Usage

var constructorApply = require('constructor-apply');

function Foo(a, b) {
	this.a = a;
	this.b = b;
}

Foo.prototype.log = function () {
	console.log(this.a, this.b);
};

var fooObject = constructorApply(Foo, [1, 2]);
foo instanceof Foo; // true
foo.log();          // logs: 1 2
