5 Free ReactJS Coding Challenges For Beginner Developer

Front-end developers play multiple roles in software companies. If you categorize these roles, you will see two broad categories.

1. UI developers
2. Business logic developers.

The UI developer implements the design, while the other implements the logic and makes the app functional. The second one requires sound logic practice to make the UI work accordingly.

If you're looking to sharpen your ReactJS skills, you're in the right place. These free ReactJS coding challenges are designed to test your ability to build business logic in React. Each challenge comes with a responsive UI built using ReactJS—but it’s not functional. That’s your job.

You might be wondering how you’ll know what to do. Don't worry! I have added user stories for each challenge. Following these user stories will help you make the UI functional.

What to do when you complete ReactJS challenge?

1. Compare your code with mine: As there are many ways to do coding challenges and build logic, you can go through my code to compare and learn to write less lines of code.

2. Add to your Portfolio: You can also add these challenges to your portfolio, but after changing the overall layout of the tool. You can use your own theme and customize it in any way to make it more impressive. Since we are using themes for CSS, you only have to replace or add variables in the theme file.

3. Share on your Twitter handle: You can also share your answer or your experience of ReactJS coding challenge on Twitter by adding #codevertiser #100DaysOfCode (if you are following the journey), #frontEndChallenges #reactjsChallenges

What if you couldn’t do ReactJS Challenges?

Ideally, you should finish these challenges on your own regardless of how long it takes, as figuring it out on your own would help hone your skills as a front-end and ReactJS developer

However, you can see hints if you are stuck somewhere in the middle. Hints will give you a better idea about how to write logic.
