Take a look at the MDN constructor page for all the ins and outs of this. The short answer is if you don't define a constructor method, your object will use a default one.

If you do not specify a constructor method, a default constructor is used.

Default Constructors:

// base classes
constructor() {}
// derived classes
constructor(...args) {
  super(...args);
}

Hopefully that helps, but let me know if you have any questions. Happy coding!
