/**
`keysToArray` returns an array of an object's own enumerable string-keyed property names. See [ECMAScript Language Specification](https://tc39.es/ecma262/multipage/fundamental-objects.html#sec-object.keys)
or [Object.keys on MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys).

## Examples

```rescript
{"a": 1, "b": 2}->Object.keysToArray // ["a", "b"]
{"a": None}->Object.keysToArray // ["a"]
Object.empty()->Object.keysToArray // []
```
