Hey! thanks for this repo of addon examples, nice

I have this question open just now: https://github.com/nodejs/help/issues/426

looking for answers, I saw your array example, is it up to date? I tried to compile it but I got this:

Hey, yes you are right this repo isn't up to date anymore.

You will probably best suited to look here and here to see how C++ add ons work.

Also feel free to send a PR with the updated API.

Best Bodo

thanks for the info!
