An ES spec-proposal-compliant Object.fromEntries shim. Invoke its "shim" method to shim Object.fromEntries if it is unavailable or noncompliant.

This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the proposed spec.

Most common usage:

var assert = require('assert');
var fromEntries = require('object.fromentries');

var obj = { a: 1, b: 2, c: 3 };
var actual = fromEntries(Object.entries(obj));

assert.deepEqual(obj, actual);

if (!Object.fromEntries) {
	fromEntries.shim();
}

assert.deepEqual(Object.fromEntries(Object.entries(obj)), obj);

Tests

Simply clone the repo, npm install, and run npm test
