One is 4 years old, another is 2 years old, and the longest one is brand new. The earlier courses were more like survey courses, providing a higher level overview of what DSA is all about. The most recent and longest course is much more in-depth. Keep in mind that even the longest course is still only going to be a high level investigation of certain algorithms and concepts. DSA is an extremely broad topic, with 50 years worth of research behind it. Recent DSA topics include graph theory, which are relatively new. Don't expect it. Any single course is going to teach you everything that you need to know about DSA. They should, however, give you a solid foundation for understanding what DSA is all about. More on reddit.com

Thanks for sharing your thoughts on this. I 100% agree with the two flaws you pointed out in the JavaScript Algorithms and Data Structures certification. I wrote many of the challenges in the JavaScript myself like 5 or 6 years ago, so I am to blame ;) We are completely re-writing the JavaScript curriculum to have a smoother learning curve, and to also include DOM manipulation and other browser-specific JavaScript. Also, everything will be taught through building project. Some examples of projects we're building (with step-by-step test suites): Learn Basic JavaScript by Building a Role Playing Game Learn Regular Expressions by Building a Spam Filter Learn Functional Programming by Building a Spreadsheet Learn Recursion by Building a Decimal to Binary Converter This is pretty labor intensive, and we've been working on it for 2 years already. But we are getting closer to shipping :) More on reddit.com
