How long will it take to study the MEAN stack?

Question

MongoDB

I know well HTML&CSS, JS at Junior level. It is necessary to write a small web service with registration in a short time. Chose MEAN stack. In principle, a complete understanding of the work of this web application is not important now (because it is a hard deadline), but I am naturally not going to write shit code either. How long will it take to learn the MEAN stack at the level of writing simple web applications (for example, some kind of advanced to-do list with registration)?

Answer 1

if deadlines are not tomorrow, then meet

Answer 2

Excellent book. The dude writes very well. And concise, and simple even for a beginner (as it seems to me).

It is quite possible to master it in a couple of weekends, the examples in it are good. Registration, authorization (+ passportjs, a useful thing). Good kick start.
Good luck!
