How to quickly learn the front/js/layout for bekendste?

For example, firm and sure step tread in the direction of the backend, like administer, write requests to lift the server. One problem - and I'm all don't like the front, and need at least some knowledge of the front.
As in a short time to understand the minimum stack front to sanity to write something and understand what is happening in this area? Should I learn the bare js/DOM/AJAX with jQuery or leave it in fashionable React/Angular? Know CSS3 by heart, or enough bootstap'a? Again, I have neither the time nor desire to read any books, I want to simultaneously consolidate all of this practice, simultaneously studying js and his ilk. I repeat, I do not need deep knowledge of the standards and fashion trends. It is banal it is necessary though something to understand, because it's necessary, but not such a deep level. There is no time, and without the need to know bash/unix/docker/nginx/sql/plgsql/postgres/python/django/flask/torndao-twisted may go or java.

A good correlation between complexity and interestingness. Not too difficult and not too easy, I mean not to chew, what variables and loops
On the other hand, is not so quickly pass, where the week on all of this at best and without a bootstap', AJAX and jQuery, although I don't know whether this jQuery

If we accept the theory of simulation of reality - you can try to hack it and upload his brain any stacks.
If you fail to follow the established procedures: pumping practice.

Go to the intensives htmlacademy if you have money
For free you can get everything you need and nothing more. The only thing - a little bit (about 300 rubles per month) to spend on it so it is unlimited in the day to have attempt answers to the exercises. It is really necessary. - Tiana_Marquar commented on June 10th 19 at 14:41
