spo-gpo

Polyfill for Object.setPrototypeOf and Object.getPrototypeOf

Usage

$ npm install spo-gpo

As a ponyfill:

const assert = require('assert');
const { setPrototypeOf, getPrototypeOf } = require('spo-gpo');
 
const obj = {};
const proto = {
  foo: function() {
    return 'bar';
  }
};
 
assert(getPrototypeOf(obj) === Object.prototype);
 
setPrototypeOf(obj, proto);
 
assert(obj.foo() === 'bar');
assert(getPrototypeOf(obj) === proto);

Globally, as a polyfill:

require('spo-gpo/polyfill');
 
const proto = {
  foo: function() {
    return 'bar';
  }
};
 
const obj = Object.setPrototypeOf({}, proto);
 
obj.foo(); // 'bar'
Object.getPrototypeOf(obj); // proto
