Do you want to sharpen your programming skills or learn a new language altogether? Are you sick and tired of examples that include Employees or Students? Do you want to stretch your limits with real coding challenges focused on improving skill and technique?
Look no further! Head over to http://www.codewars.com and sign up for an account! If you have a GitHub account (and we here at INT recommend that you do), you can sign in through that as well. Once you sign in, you will have a wide range of programming languages to choose from, as well as your level of experience as a programmer, ranging from beginner to senior developer. You will then be able to go through the many new Kata (projects) that are set up for your selected languages. As you complete projects, you gain Kyu (experience) points, forming you into a coding machine!
