I'm the creator of JSchallenger, a website where you can learn Javascript online by solving coding exercises.

JSchallenger has been around for a few years now and the number of active users is constantly growing. This and the great feedback that I receive is motivation enough to keep working on it 🚀🚀🚀

But, it's also a lot of work to maintain and keeping it growing. Besides, there are many more features already on my To-Do list.  It's just so much easier with coffee in my veins ☕☕😀
