What courses can I take on writing complex vanilla js applications?

Question

IT education

Hello everyone, can anyone recommend any courses on writing complex applications in native js?
Without jquery, without react, etc...
The site is preferably udemy/coursehunter . The language is not important. Thank you!

Answer 1

There are usually none.
Why:
1. write complex things in native js = write either crutches (unless, of course, you are a language guru and you know the patterns for building a complex application), or think with your head and connect a library or framework where 20 smart people have already predicted 90% of behavioral factors.
2. The second follows from the first, as a rule it is very expensive in production, and the cost most likely will not pay for itself for 2 reasons = setting an expensive price (a beginner will not buy, or if he buys he will refound - because he will not understand), but a professional is most likely will not buy - he encounters this at work, and the courses are for beginners.
Solution: go to github, look for vanilla applications written in js, and parse the history of the application creation by commits.
