Solving exercises

Learn how to solve exercises on Exercism

The primary way in which Exercism helps you learn is by solving exercises.

There are two ways to solve exercises on Exercism:

  1. Online via the website's in-browser editor
  2. On your local machine via the CLI

Which option should I choose?

There are different trade-offs between using the online editor or CLI:

Online editor CLI
Installing No Yes (e.g. SDK)
Editing Browser Your preferred editor
Testing Run tests on website Run tests locally
Debugging Limited support (only for some tracks) Full support (depending on your environment)

In general, the online editor is ideal for starting new tracks, whereas the CLI-based approach is great if you want to use your own, personalized coding environment.
