An ES2017 spec-compliant Object.entries shim. Invoke its "shim" method to shim Object.entries 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 spec.

Most common usage:

var assert = require('assert');
var entries = require('object.entries');

var obj = { a: 1, b: 2, c: 3 };
var expected = [['a', 1], ['b', 2], ['c', 3]];

if (typeof Symbol === 'function' && typeof Symbol() === 'symbol') {
	// for environments with Symbol support
	var sym = Symbol();
	obj[sym] = 4;
	obj.d = sym;
	expected.push(['d', sym]);
}

assert.deepEqual(entries(obj), expected);

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

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