setprototypeof

Polyfill for 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.

Usage:

$ 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 from 'setprototypeof'

Similar packages

Other packages similar to setprototypeof

object-assign

The object-assign package is used to copy the values of all enumerable own properties from one or more source objects to a target object. It is similar to setprototypeof in that it is used for manipulating objects, but it does not change the prototype chain.

lodash.assign

Lodash's assign function is similar to object-assign and is used to assign own enumerable properties of source objects to the destination object. Like object-assign, it does not deal with the prototype chain but rather with copying properties.

util

The util package is a collection of utilities originally for the Node.js standard library. It includes util.inherits, which is a method that allows you to set the prototype of a constructor to an object, creating a prototype chain similar to what setprototypeof does, but specifically for constructor functions.
