Most used frameworks, libraries and platform?

Question

I would like to know which of the ones above are most used. Also which ones are a must-know for creating modern web applications. And if somebody is listing more, i would like them to type the level of complexity also, so anyone who is reading this post can pace themselves.

Answer 1

In regard to websites, although it's not where I specialize, this is what I typically find myself using:
- NodeJS
- jQuery
- React
- Angular
Beyond that, my specifications for projects are usually very particular, so I just build up whatever I want from that foundation most of the time. Ultimately, it depends upon the project and I'll use/learn whatever is required for it.

Answer 2

I use C# mostly as a backend.
- aps.net core 2 for backend
- entity framework core
- automapper
- Angular2 for frontend
- Bootstrap3
