I feel like a week isn't anywhere near close enough but depending on what you want to do it gets you to start tinkering. Ironically I do wish that I had started working on embedded with microcontrollers than starting with web purely because there isn't space for absurd abstractions.

On web even the DOM API is a huge abstraction over rendering calls to OpenGL/DirectX/Vulkan and I never could grok what is happening with the DOM API until I played with the underlying tech and learnt about trees and parsers and how that would be stored.

I still use the DOM and love the abstraction, but sometimes I just wish I could use an immediate mode approach instead of the retained mode that the DOM is...

Someone with a week of knowledge, or even someone who has spent 10 years building react may not understand half of that unless they have actively tried to learn it. Thwy might have an idea if they had formal education but a self taught programmer. They have been building houses using lego blocks, I you give them mortar and bricks you are setting them up for failure.
