add a static method to a class in javascript

In JavaScript, static methods are methods that are called on the class itself, rather than on an instance of the class. To add a static method to a class, you can use the static keyword followed by the method name.

Here's an example:

index.tsx
class MyClass {
  static myStaticMethod() {
    console.log('Hello, I am a static method!');
  }

  // ... other class methods ...
}

// To call the static method:
MyClass.myStaticMethod(); // Output: "Hello, I am a static method!"

In the example above, the myStaticMethod method is added to the MyClass class using the static keyword. This method can then be called directly on the class itself, rather than on an instance of the class.

Note that static methods cannot access the this keyword, as they are not tied to any specific instance of the class.
