Answer 2

The first thing to start with is to forget about MVC micro frameworks like Laravel / Yii, etc.
If Laravel is a fast fighter, then in comparison, WP is an aircraft carrier. Which can carry a functional load on its board like 100 Laravel.
Hence the difference in architecture - in WP it is many times thicker. It is much more difficult to study it.
A student without preparation can raise a site on WP. However, when the question of some kind of development arises, WP is much more difficult.
And most importantly, it implements all OOP paradigms. The most important thing is the principles of component-oriented development. Which are based on Event Driven architecture. This is what Alain Kay talked about 20 years ago and called it OOP. But only a few around the world understood what he meant. And WP is one of the few platforms that has managed to implement these ideas correctly. Its entire development is based on messaging - through hooks. And all logic beats on components.
There is a place for MVC, but how it works there is not a bit like MVC ala Laravel / Yii ...
Therefore, the most important thing is to forget about the principles of Laravel and other fashionable MVC trends. And immerse yourself in the architecture that has conquered the world. The blessing of articles in bulk. You can even start from the cradle. But to become a pro in this business - you need years of practice. There are only a few good specialists in this topic.
