— Hmm, not sure!

—

As I understand it class is just a special function, and assigning a property to an uninstantiated class should get you the same results as assigning a property to a function definition.

— Uuuh noo

— Which... I have never tried, haha

— It creates a static method

—

class MyClass {
  static myMethod () {
    return 4;
  }
}

equivalent to:

function MyClass() {
};

MyClass.myMethod =
  function myMethod() {
    return 4;
  };

— Except second one can run as a function (without new) as well

— That's the only difference

— Heh, static methods AND instance methods can all be changed at runtime dude

— I see

— For static, that is not something I expected. It seems I know less about class syntax in JS than I thought I did

—

function MyClass() {
}

var myInstance = new MyClass();

MyClass.prototype.foo = () => 'bar';

myInstance.foo(); // 'bar'
