Implementing Python's dir() for classic JScript

[F. S. Farimani]

With little documentation available for JScript a dir() function, like the one in Python, could be really handy. I was thinking if I could implement such a function to list all the properties and methods an object carries.

I looked at the options on this page

Sadly the Object.keys() and Object.getOwnPropertyNames() methods don't exist in JScript. And the other option using in operator:

function dir(inputObject) {
properties = [];
for (property in inputObject) {
properties.push(property);
}
properties.sort();
return properties;
}

returns an empty Array. I would appreciate it if you could help me know if/how this could be implemented in JScript.


P.S. I had previously asked this question here on SO

but sadly it has been removed with no further explanation.
