What are class variables in JavaScript?

Class variables in JavaScript are properties that are shared among all instances of a class. They are defined using the static keyword.

Can you give me an example of how to use class variables?

Sure! Here's a simple example:

class MyClass {
    static classVariable = 'I am a class variable';

    static displayClassVariable() {
        console.log(MyClass.classVariable);
    }
}

MyClass.displayClassVariable(); // Outputs: I am a class variable

What is the difference between class variables and instance variables?

Class variables are shared across all instances, while instance variables are unique to each instance of the class.

Are there any limitations to using class variables?

Yes, class variables cannot be accessed directly from instance methods without referencing the class itself.
