Can you look at this question? https://stackoverflow.com/questions/26655534/how-this-js-jquery-syntax-work
I tried to show every point which was not clear. Most of time I read a university book they were completely unclear. The teacher were giving everything as understood.
But this is my personal idea. I would like to ask if there are resources, tools, website or anything else for improving the quality of slides, books or eLearning in the direction I've showed in the question on StackOverflow.
Can I open such a question here?
