JavaScript Angular Design Patterns [closed]

I am new to UI concepts and have some queries listed below

1. Is MVC, MVVM or MVP a design pattern or framework?
2. How many design patterns do JavaScript have? is there any reference from where i can learn design patterns
3. What design pattern do angular 9 follow? as some websites/questions on stackoverflow says MVC some says MVVM or some says Observable etc. Bit confused with it
