A simple cross platform implementation to set the prototype of an instianted object. Supports all modern browsers and at least back to IE8.

$ npm install --save setprototypeof

var setPrototypeOf = require('setprototypeof');

var obj = {};
setPrototypeOf(obj, {
	foo: function() {
		return 'bar';
	}
});
obj.foo(); // bar

TypeScript is also supported:

import setPrototypeOf = require('setprototypeof');
