JS call static method from class

I have a class with a static method:

class User {
  constructor() {
    User.staticMethod();
  }

  static staticMethod() {}
}

Is there an equivalent to this for static methods (i.e. refer to the current class without an instance)?

this.staticMethod()

So I don’t have to write the class name: “User”.

Answer

From MDN documentation

Static method calls are made directly on the class and are not callable on instances of the class. Static methods are often used to create utility functions.

For more please see=> https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes/static

You can do something like this => this.constructor.staticMethod()); to call static method.

class StaticMethodCall {
  constructor() {
    console.log(StaticMethodCall.staticMethod()); 
    // 'static method has been called.' 

    console.log(this.constructor.staticMethod()); 
    // 'static method has been called.' 
  }

  static staticMethod() {
    return 'static method has been called.';
  }
}
