As near as I can tell, "understanding" is not (generally) considered to be a prerequisite for being any sort of developer. If someone decides to make a website and looks up resources for it, the first thing they're probably going to discover is either something faddish and trendy but completely insane and misguided (SPAs) or something which should be decent but has obnoxious functionality added with JS (e.g. cookie banners, tracking, floating headers), possibly gratuitously broken without JS (let's hide the content with CSS and then show it with JS!) because whoever created it has no comprehension of their craft.
