> why bother learning two paradigms Objection. Your React is ultimately turning into HTML so you DO have to learn HTML + CSS. You just have an abstraction over it.
That's like saying my C# is getting turned into CLR bytecode, so I do have to learn CLR bytecode because I have an abstraction over it. Yet I know roughly what it is, but I couldn't begin to actually write the stuff myself. Good abstractions mean you don't have to worry about the layer below. Now of course it's not really the case that React holds up to being a good abstraction, especially when it comes to CSS and st…
For a good part of your career this is true, but eventually you will need to justify your senior salary by being able to debug react via looking at library code itself, or understanding the event bubbling under the hood, or figure out why the output css isn't working.
Saw a video, wish I could remember who, someone developing a game in c-something. There was some bug they couldn't figure out so they jumped into I guess the assembly for that block of higher abstracted code, and was able to find some kind of memory issue. Vague, sorry, but point is I remember being really impressed, thinking oh shit yeah if I really want to be an expert in my field I better be able to really understand my stack all the way to the bones.
