Awesome websites to put your coding skills to the test!

Practice, practice, practice.

The number one thing that is consistently preached to anyone learning how to code.

Practising your coding skills is essential for improving as a programmer, as watching tutorials can only take you so far.

But what better way to practice than to get yourself out of your comfort zone and put yourself to the test?

Introducing coding challenge websites.

Coding challenge websites are designed to have bite-sized coding problems for you to solve. These can be anything from simple algorithmic challenges to complex puzzles that test your ability to think critically and logically.

What’s more, there is usually an element of competition, where you can compete with others to gain points for the most challenging you can complete. It’s like playing a sport! 🏓

Many of the challenges you will face are also often used during the interview process for developer roles. So the more you get used to them, the better prepared for potential technical job interviews - it's a win-win!

I’ve put together a list of my favourite 7 coding challenge websites to sharpen your skills.

Let's take a look!

#1 - Codewars

Codewars is an online platform that helps developers hone their coding skills. It features various challenges, or “kata”, for users to complete. These katas range from beginner to advanced levels and cover a wide range of topics, such as algorithms, data structures, and more.

Codewars is an excellent way to improve your programming knowledge and skills. It encourages you to think critically and creatively and to practice problem-solving. It also allows you to connect with other coders and learn from them.

In addition, Codewars offers a ranking system called “kyu” that allows you to compare their progress with others. This can be great motivation for practising and allows you to measure your own progress.

Overall, Codewars is a great way to challenge yourself and learn new coding techniques from others.

#2 - LeetCode

LeetCode is a great website for anyone looking to sharpen their coding skills. It provides coding challenges that can help you improve your problem-solving skills and give you a deeper understanding of data structures and algorithms.
