Which of these 2 sites to learn JavaScript?

After three months of training layout on YouTube, there is a need to start learning JS.
But unfortunately for itself, had not found a suitable Russian-language channel where details would be taught from scratch in JS, probably badly searched, can throw options.

Then decided that still will be better to study the written learning options, and after monitoring found 2 options: 1 and 2.

What do you think where is better to study? The problem is that I am inclined to the second option, it seems to me (based on a quick and sloppy analysis) that there is more strukturbank and a lot of tasks, but practically no feedback. While the first option suggest every one on the Internet, although briefly passing through the materials found there or 4-5 high, or they do not.

P. S. a couple of days ago I started reading a book "Learn programming in JavaScript" by Freeman and Robson, yet like everything, but still uncomfortable jumping from book to laptop, I think books are better read to consolidate the material.

To start can anyone still will have to continue on "you don't know js", MDN and so on. The developer does not cease to learn, for JS new specs come out every year, plus frangaki updated and changed.

I can advise that helped me at the time. Since I have the JS was very tight, straight from scratch, I did a collaboration from the textbook and examples on codewars.

Explain: (example) - you have a Chapter in the textbook(any training service), for example under the name arrays(functions, objects, strings, etc) - read, if slow learner - I read it again, and codewars, or network to find a practical problem.

The bottom line: the book is very good, but the problem, without which, no hard errors, googling and having received of blood and sweat that comes out with each task - the path will be much longer. Use the Pareto principle 20\80. 20% will be spent on reading those documentation, 80% of this code. If 20% is not enough for you, and information is not enough - calibrate the interest until you reach the facilities. But to learn the language - you have to write code.
Hello!

Just do not understand how on codewars you can find tasks exactly on a particular subject ( arrays, functions..)? - Robert.Crook commented on April 3rd 20 at 18:38
@Robert.Crook, Like does, use Google - edwina67 commented on April 3rd 20 at 18:41

At this stage - no matter where the stuff comes better. When some basis has already been you will understand what to read next.
