Why #JavaScript doesn't expose a static Object method which returns the number of the object own enumerable properties?
I find `Object.keys(obj).length` a bit clunky.

@abozhilov I must admit, I don’t understand why static methods in #javascript are that way at all. Why Object.keys(obj) and not obj.keys() as one would have in #java or #python?
@jmft Basically because it would break the web. There were popular libraries which extended `Object.prototype` and if those method were introduced through `Object.prototype` a lot of websites would stop working correctly.
