Reflect.ownkeys NPM

reflect.ownkeys

An ES2015 spec-compliant Reflect.ownKeys shim. Invoke its "shim" method to shim Reflect.ownKeys 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 ownKeys = require('reflect.ownkeys');

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

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

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

if (!Reflect.ownKeys) {
	ownKeys.shim();
}

assert.deepEqual(Reflect.ownKeys(obj), expected);
