Say I want to learn web scraping. Now if I try to start, I see there are several layers of fundamentals and several potential paths, all of which seem equally important. Where do I start? What platform should I use? Should I start from the DOM and HTML parsing and go ahead from there, or should I start from learning Python libraries built for it as so many books and tutorials advise? Going one layer deeper, do I need to learn data structures before anything else? JavaScript and APIs? The fundamentals of TCP networking? Regex?
It's all too overwhelming at times.
