Objective

Throw InvalidArgumentException in a JavaScript method like one does in Java or similar languages.

Background

I have been trying to familiarize myself with JavaSctipt error handling, and I know I can throw exceptions using the throw keyword.

To achieve this, I read the throw documentation on MDN and the Error documentation on MDN as well.

Problem

So far this is my code:

if (mySize >= myArray.length)

    throw new Error(InvalidArgumentExcpetion - BANG!!!!);

This code has some problems for me:

1. I have the text in the exception itself. Right now I have BANG, but tomorrow I may want BONG and if I decide to change it, I have to look everywhere!


2. I am using an Error, and not really a new object with the type InvalidArgumentExcpetion. Is this the correct way?

Questions

So now I am confused.

1. Should I create a new object like in the throw documentation, or create an Error Message?


2. Doesn't JavaScript have a InvalidArgumentException object that I can use?


3. How should I proceed in order to have a maintainable way to throw errors that uses ECMA6?
