What’s a good way to extend Error in JavaScript?

I want to throw some things in my JS code and I want them to be instanceof Error, but I also want to have them be something else.

In Python, typically, one would subclass Exception.

What’s the appropriate thing to do in JS?

In ES6:

class MyError extends Error {
  constructor(message) {
    super(message);
    this.name="MyError";
  }
}
