Can a mutable static class variable be created in JavaScript?

I have an idea similar to this concept:

class Example {
    static var X;
    static setX(value) {
        this.X = value;
    }
    static getX() {
        return this.X;
    }
}

This allows the variable to be stored within the class and easily modified from outside.

Answer №1

To achieve the desired result, simply use the following code snippet:

class Example {}
Example.value = 7;
