What are the basic things for sites you need to be able to do with JS and resources to learn?

Question

JavaScript

Good afternoon!
I continue to study js,
the main source is learn.javascript.ru,
I do simple things for practice - tic-tac-toe, memo, shopping list, etc. But I also want something more practical.
Can you please tell me what most often needs to be done for a typical site, what are typical tasks - a modal window, a carousel, form validation? what else?
And where is the best place to watch it?
I understand that there are typical solutions and there is no need to reinvent the wheel.
thanks in advance
