Define a static class variable on javascript

Question

I'm starting using the new way of OO in javascript by following this tutorial. This new way of OO of javascript follows the ES6 specification.

Follows a sample of my code:

class SomeClass{

        static SomeFunction(data){
            this.data = data;
        }

}

What I want is to make the variable this.data static.

Is any way that I could do that?

Because the new class keyword is just syntatic sugar you can do

SomeClass.staticVariableName = value;

Put this outside of the class, if you put it in the constructor, then it will only be initialized when you create at least 1 instance.

Side note: if this is a client side code, then I just want to warn you that you shouldn't authenticate people client side, because it's terribly insecure.

It is just an example: this not really "match" with a really case. I ask this because the tutorial does not explain it. Maybe is better change the case to become more understandable. I will test and see the if results

@Ricardo Again, I just wanted to warn you if you intended this code for production
