  • Quality Variability
    The quality of user-submitted challenges can be inconsistent, meaning not all katas are equally useful or well-designed.

    While great for practice, Codewars does not provide comprehensive tutorials or in-depth explanations, which are often needed for mastering complex concepts.

    The addictive nature of the platform can lead to spending excessive time on solving challenges, potentially detracting from other learning activities.

  • Of recursion and backtracking
    Recently, I was working on a coding kata on codewars.com. Early on, I started thinking that a potential solution might utilize recursion, a concept that involves a function calling itself. However, I quickly realized that my grasp of recursion was not as solid as it needed to be for this task. In this post, I will share the insights gained from deepening my understanding of recursion while working through the kata. - Source: dev.to / almost 3 years ago
