Ratings and reviews

I'm not satisfied, totally money waste. It has some basic tutorials. but it’s JS compiler has some issues. i won't recommend it.

It's complicated to learn and this is an absolute scam. Don't buy this. You cannot get a refund after buying like why is that? For smart people who understands JavaScript, you do your own thing but this is a warning for newcomers

Great Idea with this Application to create a Muscle Memory in Javascript, i would really appreciate if the developers would add a small text with a reference to where we've read what we've just tried to answer and had wrong(Quiz)
