Codewars is an online platform designed for programmers to improve their coding skills through practice and challenges. Users can solve coding problems, known as "katas," which vary in difficulty from beginner to advanced levels. The platform supports multiple programming languages, allowing users to choose their preferred language for solving challenges. In addition to solving problems, Codewars encourages community interaction. Users can create their own katas, share solutions, and discuss different approaches to coding challenges. This collaborative environment helps learners gain insights and improve their coding techniques while engaging with a global community of developers.
