Where to start studying?

Question

JavaScript

At one time I studied html, css, php, mysql and one php codeigniter framework.
I always wrote sites at the beginning either in pure php + mysql or, when I studied CodeIgniter, on it.

Then I didn’t develop for a long time, I was busy with another field of activity.
Now I see all sorts of nodejs, meteor, react, angular and other buzzwords have appeared.

Unfortunately I don't know javascript. I understand all this is connected with him.
Tell me where to start, so that I can now study all this and start writing modern sites, because. I realized my old knowledge is not enough for this, you need a node, etc.

Answer 1

I learned jQuery from Anton Shevchuk's video tutorials. But you need to understand that you can’t just take a look at the lessons and start writing. Look at the lessons, come up with a project for yourself, problems will arise during the work on the project, get into the reference books, search the forums, a couple of projects and become an expert
