Object.setPrototypeOf
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');
