Exercism

Programming is hard. With practice it gets easier.

Exercism gives you hundreds of practice problems in over 30 programming languages, and a place where you can get feedback on your solutions.

Exercism is especially well-suited for three types of practice:

gaining fluency in your first programming language
ramping up in a new programming language
developing the skills to be a great lead developer: code review, refactoring, and mentoring

Using Exercism

The process happens in two places.

Solve exercises in your local development environment.
Discuss solutions on the Exercism website.

Once you submit the solution to an exercise you can:

learn by listening: receive feedback on your code.
learn by reading code: browse all the other solutions to exercises you submitted solutions to.
learn by sharing your experience: provide feedback on other people's code.

Even in the most trivial exercise, there are many important things to discuss. Simplicity, naming, readability, idioms, good use of existing libraries, performance, and much, much more.

Get started using exercism on the exercism.io website.

Getting Help

Are you stuck trying to solve an exercise?

Submit the unfinished solution and describe in a comment on the website what you tried, and where you're stuck.

Or jump into the support chat, and we'll try to help you out.

Did you find a bug?

That's always frustrating. Go ahead and open a GitHub issue, and we'll help figure out what's going on.
