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);
