When could these be useful?

- To test yourself/test your coding abilities under pressure
- For beginners looking for a fun way to learn React
How do they work?
The scaffolding is done for you. Simply run yarn in any of the directories to start the application. Each application has a README with its requirements.
Some might require connection to external APIs, but all information will be provided in the inididual challenge readmes.
Have you got the solutions?
I have completed all the coding challenges to a high standard. If you're interested in being invited to the solutions GitHub repository, get in touch with your GitHub username.
Why are the solutions invite only?
People use these challenges for interviews. By putting the solutions behind a collaboration wall/invite-only repository we can discourage candidates from simply looking up the solutions.
Why does it take so long for updates/new challenges?
I work on these challenges & solutions in my spare time, on top of a full time job and all the other stuff. Because of this, I don't always get a lot of time to maintain and add new challenges. Interested in becoming a collaborator or submitting your own challenge? Reach out below.
