React Coding Challenges 👋

A series of React.js coding challenges with a variety of difficulties. Deep dive into the why here.

The Challenges

Easy 🙂

🚀 Rocket Ship

Unecessary re-renders, fine grained control

Medium 😐

🌙 Dark Mode

State/Shared State, DOM manipulation

Data visualisation and graphing. API usage

Hard 😬

🎧 Spootify

Loading state, API usage

🤖 Chatter

Web sockets, events, callbacks & React hooks. Talks to Botty

When could these be useful?

• Usage as short coding exercises, such as for interviews
• 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. Get invited to the solutions repository at solutions.alexgurr.com.

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. We track current/past collaborators, meaning if you want to check if a potential candidate had access/looked at the solutions you can get in touch and find out.

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.
