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

* Non-object values are coerced to objects.
|

*
|
|
* @param {object} object The object to query.
|

|
* @example
|
|
* function Foo() {

* this.a = 1;
|
|
* this.b = 2;
|
|
* }
|
|
* Foo.prototype.c = 3;
|
|
* keys(new Foo); // ['a', 'b'] (iteration order is not guaranteed)
|
|
*
|
|
* keys('hi'); // ['0', '1']
|
|
* keys([1, 2, 3]); // ['0', '1', '2']
|
|
* keys({ a: 1, b: 2 }); // ['a', 'b']
