Where can I watch a good video about AngularJS 2/4?

Question

Angular

Recently, slag comes across: tutorials with steps on how to write html and what a closure is. We coded a simple app, we did it. Those. the videos are all sharpened for the most part for people with near-zero programming experience.
We need a video that would sensibly explain how to write components, how to integrate them into modules.
How to ensure connectivity? How to approach application design, modularization.
To be sensibly explained what, where, when, why. How to do it right.
There is a lot of material, but there is no time to watch everything, the mana is also decent, I read it, but there is no complete picture.
You need an explanation from the top down, and not from the bottom up, as is customary in conventional courses.
The language is English or Russian, it doesn't matter. A good enlightening article will also help.
