How to make array from class variables

Question

I want to create an array from existing values of class vars in typescript

Eg:

export class example{
  static readonly a = 'aval';
  static readonly b = 'bval';
static readonly c = 'cval';
}

TO

exampleArray = ['aval', 'bval', 'cval'];

Note: I want to make it like access all vars values of class in one go and put it in array not like [example.a]

I hope you are not using a class with only static class variables in your actual code. If that'd be the case then you should use a plain object instead. — Felix Kling

Object.values(example) should work

I don't think it will work, Because the question is how to make an array from class not object

@Wajid ... A class in JavaScript is an object too. Thus a class with just static properties has to be treated like an object; in this case one actually should use a plain object at first place.

class in JS actually a function and function is an object), so static properties of class becomes properties of function/object ⚆ _ ⚆. Please try it, you will see that it works

@Wajid console.log(class A{} instanceof Object) gives true though...

Object.values(SomethingClass);

Will give you an array of the values. But just FYI - I believe it only works for static class members.

To get class members that aren't static, you'd need to instantiate it first.

Object.values(new SomethingClass());

That would give you only the non-static members.

@Wajid - it works, I tested it before answering :-)

@Wajid what makes you think a class is not also an object?
