Very good information for programmers or developers. Thanks.
When we follow a tutorial or course it gives us a feeling that we understood things very well. But when the time comes to apply the knowledge to solve real word problems or projects, sometimes the situation becomes complicated.
We learn and retain more by applying our knowledge than just following someone. I always prefer short cookbook type tutorials than long, boring tutorials. As it helps me to understand the particular concept clearly and I can effectively build a thing by connecting those knowledge.
Also we should leave tutorial hell for more productivity in our actual work.
