About jQuery - do not listen to this nonsense that jQuery does not cake, or that jQuery is outdated. All this is just the emotions of individual developers. Solving business problems, you will quickly realize absolutely no need to try again to solve the problems that have already been solved and thoroughly tested in this library. The rejection of jQuery can be justified only in 3 cases:
1. If your project will be run only on modern browsers (no IE 9, 10, 11 or God forbid 7 and 8, etc.)
2. If you really need to write a couple lines of code
3. If you are using some big framework, which offers its own API.
In all other cases, jQuery is fully justified and necessary.
