JavaScript Codewars practice

The best way to improve our problem-solving skills is to practice, practice, practice. Many developers continue to do frequent practice on small sample problems, some even using them as a daily warmup before beginning their daily routine.

One of the common interview scenarios for developers is a coding question or challenge. During an interview, you may be asked to code the solution to a small problem or you may be given a small application to create over a few days and turn in.

Both of these scenarios require you to begin a habit of practicing reading and solving coding exercises.


  • Exercise and improve your problem-solving skills
  • Prepare you for interview coding questions
