Those two parts demand the most seamless and direct expression, and continuous feedback. It’s not quick, it’s deliberate and diligent. That’s what I value and aspire to.
Let's say we needs some forms. Nothing to fancy. Consider 2 options: React+JS+Redox+formLib+... and Elm.
It just some banal forms, I agree. But having to come back to it may months/years later I much rather see back the Elm situation.
Typing helps a lot here. Small scope project too.
Now it seems this "build in minutes" uses JS and PHP. Sorry, but both are terrible choices for long term maintainability.
To the instrument analogy it's like Beethoven's 5th. Almost anyone can play the beginning on the piano with a few minutes of fooling around (dun dun dun da....). But to actually play the entire thing well will take years of practice because it's the other parts that are hard to get right and must be correct to work.
