The most tiresome thing in #webdev is picking the techstack. So many choices to make: plain #javascipt or a more restricive language like #typescript , which ofc is often depending on the overall frontend framework to use: #svelte , #react , #preact , #solidjs ?
Or do one completly deviate from the classical way and use rather a techstack via #wasm , such as #rust with #dioxus ?
So many questions to answer and that still is only the js side of things, you then have to think about your css framework (if you want to use something like #tailwindcss ), your font choices, and ofc if and what styling library you actually use ontop of our frontend framework; e.g. #bootstrap , #blueprintjs , #tabler.io and so on.... which also often depends on your framework of choice!
