Yes, totally.
I was just surprised that something that was so obvious and "core" to the web to me (I'm in my forties) was unknown by others who are doing things which I consider more advanced or complicated as doing requests through redux, rxjs, etc.
It's just surprising to me. Feels like we're failing at teaching web dev by starting from the top instead of from the bottom.
Like if we're teaching physics by starting from relativity and quantum mechanics without having thaught people to do basic maths.
