JSPM – object-keys@1.1.1

Package Exports

object-keys
object-keys/isArguments

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (object-keys) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

#object-keys

An Object.keys shim. Invoke its "shim" method to shim Object.keys if it is unavailable.

Most common usage:

var keys = Object.keys || require('object-keys');

Example

var keys = require('object-keys');
var assert = require('assert');
var obj = {
    a: true,
    b: true,
    c: true
};

assert.deepEqual(keys(obj), ['a', 'b', 'c']);

var keys = require('object-keys');
var assert = require('assert');
/* when Object.keys is not present */
delete Object.keys;
var shimmedKeys = keys.shim();
assert.equal(shimmedKeys, keys);
assert.deepEqual(Object.keys(obj), keys(obj));

var keys = require('object-keys');
var assert = require('assert');
/* when Object.keys is present */
var shimmedKeys = keys.shim();
assert.equal(shimmedKeys, Object.keys);
assert.deepEqual(Object.keys(obj), keys(obj));

Source

Implementation taken directly from es5-shim, with modifications, including from lodash.
