 * Creates an array of the own enumerable property names of object.

 * - does not give any special consideration for arguments objects, strings, or prototype objects (e.g. many will have `'length'` in the returned array)
 *
 * Contribution to minified bundle size, when it is the only function imported:
 * - Lodash: 3,326 bytes
 * - Micro-dash: 148 bytes
