js call static method from class

Chris picture Chris · Apr 25, 2017 · Viewed 36.8k times · Source

I have a class with a static method:

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

  static staticMethod() {}
}

Is there something like this so 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'.

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.';
  }
}
