How to learn WP_Query?

Question

WordPress

I started to study WP_Query in detail. And I came across the fact that a huge number of actions, filters, properties, methods are listed and, of course, they are not remembered. Some are not understandable at all without some example in the code and information about where to use it.
I met with such an opinion: "Well, now you know that there is some kind of hook that the SQL query filters and when you need it, you can find it."
Is this true? Is there any way to consolidate knowledge? Or maybe there are good examples somewhere.

Answer 1

How about the official documentation:
https://codex.wordpress.org/Class_Reference/WP_Query

Answer 2

1. Understand the possibilities in general
2. Know where to look (Codex, hookr.io, wp-kama.ru etc)
3. Read the manual as tasks arrive (see point 2) and solve problems correctly
Over time, it will settle in your head . Practice is power.
