Creates an array of the own enumerable property names of `object`. **Note:** Non-object values are coerced to objects. See the [ES spec](http://ecma-international.org/ecma-262/7.0/#sec-object.keys) for more details.
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']
