What are your favorite coding challenge sites?

Madza on October 14, 2020

Some time ago I did a lot of Codewars in my spare time. It's a great platform with loads of challenges in different languages, a nice reward system...

Hey fellow devs! Thanks a lot, Madza, for gathering those up!

I want to add another project, that I created together with BandaWorks, it's called Housework Undoer.

🏗️ Housework Undoer is a project challenging you to build a full-fledged app.

📖 At the same time, you won't deal with just coding - you'll be going through a meaning story, that will introduce you to your users, explain their problem and this way help you learn how to build a product with users in mind.

🤖 To make more close to the real development workflow, we organized the project into multiple tasks, each one presenting you own challenges.

The project is still young, so we are looking for feedback.

We also willing to help if you have any question through the project or will struggle with something 😉

Take a look: banda.works/housework-undoer

codingame.com/ can help you have fun learning: The purpose of games can be achieved through programming. You can practice many languages and types of tasks in it. My favorite is Clash of Code, where you have to solve the task more skillfully than others + you can also see the solutions of others after the game (if they shared it).

I'm a huge fan of codingame.com. The site is really polished and the competitions are quite addictive. I have spent many a late night working on trying to achieve a better rank.

⚠️Beware CodeSignal/CodeFights/BrainFights, they banned hundreds of repositories with solutions from GitHub before.

That's because they are showing all solutions and also using code from codesignal.

My post it's more related to show how we can solve a problem in multiple ways and how to measure performance.

I would say that my favorite coding site is codewars. It's a great platform to hone your skills in a language and get comfortable with it. Also, some of the challenges I encountered there were quite unique and interesting. Also hackerrank, codingbat and codingame.

Mostly Leetcode. I've used it to prepare for interviews and I extract problems from it for my articles.

I haven't tested much the others. Only Project Euler, but this is very math heavy - which I like, but not ideal for interview preparation.

I love Exercism in that I learnt how to actually run code on my machine.

Other code challenge websites seem to think otherwise.
