By interactive tutorial I mean, tutorials that contain unit tests for the tasks that you are supposed to achieve in that tutorial. One example is LearnYouNode. It is a tutorial series containing 13 problems that teach you Node.js
Each problems has fixed task(s) that you need to complete and there are unit tests in place to check whether you've completed the tutorial properly, there is no guessing work.
So, do you like such tutorials? Have you ever seen similar ones? I'd really like to know.




In my opinion they are at best okay. Maybe 6/10 for the best ones.
If the tutorial is good, such as (in my opinion) Free Code Camp, then they are okay.
I remember doing LearnYouNode in the past and hated it. As a complete beginner to Node and inexperienced programmer, I felt like I learned some very specific and shallow stuff without any background as to how the thing works and how to use it in a project. To it's defence, maybe the target audience is experience programmers who are new to Node.
On the other hand, challenges like LeetCode and such are very good. They are not tutorials though.
