Thank you for the PR @zeabdelkhalek!

It seems like you based this language of Groovy. That's obviously a good choice, but please adjust the tests. It seems like most of them have just been copied over, so please adjust them. Btw, to update tests quickly, just run npm run test:languages -- --update.

Also, code style. Please copy the code style from languages. npm run lint:fix is probably a good start.

I found a few minor things, but otherwise it's good to go.

Also, please run npm run build to update the minified files.
