Codewars, Hackereath, and Euler are my favorites whenever I have some time to spare I do a few challenges.

As a matter of fact being self taught I had never heard of unit testing in programming books when I was learning. I learned unit testing while doing codewars challenges.

they should do a code-challenge-website "real world" edition:

  • you have to wait 3 days for the confirmation
  • the task changes slightly halfway through solving it

Codewars and HackerRank are my favorites. I also like TechieDelight Is not an interactive site, but it has 500+ data structure and algorithm questions with their solutions and explanations.

I've been using HackerRank as a practice on functional programming, as some problems are simple and more real world oriented problems.
It is a pretty nice tool for practicing, yet I didn't try any other in some time now (about 2 years without trying any code challenge website)

All good sites. Another fun one is code combat where you learn to build a game. After going through some of the basics you have the tools to go off a build your own level, the code can be as simple or complex as you want it to be.

This is a great list of sites for coding challenges!

I've got a site called Frontend Mentor that I'd love to hear your thoughts on if you're interested in taking a look. It's very new, so is nowhere near as big or complete as these other sites.

But seeing as you're a front-end developer, it might interest you! 🙂

Hackereath is nice because you also have nice explanations on how algorithms work.

Hi, thought I might add one to the list:
warriorjs.com/ where you code adventures and solve problems in a game format.

Another bonus of Codewars are the tools and guides available for writing your own katas and test suites. It's a lot of fun watching people solve your puzzles.
