Extending Error in Javascript with ES6 syntax & Babel

Question

I am trying to extend Error with ES6 and Babel. It isn\'t working out.

class MyError extends Error {
  constructor(m) {
    super(m);
  }
}

var error = new

That class MyError extends Error {…} syntax is correct.

Notice that transpilers still do have problems with inheriting from builtin objects. In your case,

var err = super(m);
Object.assign(this, err);

seems to fix the problem.
