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          


        

Answer 1

Combining this answer, this answer and this code, I have made this small "helper" class, that seems to work fine.

class ExtendableError extends Error {
  constructor(message) {
    super();
    this.message = message; 
    this.stack = (new Error()).stack;
    this.name = this.constructor.name;
  }
}    

// now I can extend

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

var myerror = new MyError("ll");
console.log(myerror.message);
console.log(myerror instanceof Error);
console.log(myerror.name);
console.log(myerror.stack);
