Introduction

Coding challenges are essential to programming, as they help developers improve their problem-solving skills, logic, and creativity. Participating in coding challenges is a great way to improve your programming skills, learn new approaches, and showcase your talent to potential employers. These websites are useful for everybody, whether you are new to coding challenges or a professional programmer. Below is a list of some popular coding challenge websites with a short description of what each one offers.

Edabit

they are like Duolingo for learning to code. When learning to code, most people get stuck on the "bridge" between memorizing syntax and understanding the logic that makes it all work. Most beginners jump from memorizing syntax directly into making stuff (or trying) without fully understanding how syntax is used to solve problems. In other words, they haven't learned how to think like a programmer, yet they're trying to solve problems like a programmer. Edabit was created to bridge this gap, while also making the process fun and addictive. Learn to code with 10,000+ interactive challenges. Gain XP, unlock achievements and level up. Their bite-sized challenges are a shortcut through the coding maze.
