I've been using React for just about a decade at this point and IMHO the thing that makes it a killer framework isn't one feature but all of them combined that makes it possible to move very fast in product development with multiple contributors. It's easy for devs to pickup relative to other languages, yes there are footguns but for the most part they are in the minority and you figure out the "Rules of React" pretty quickly and avoid them.

Remember folks, were all talking about our figurative drills and hammers in this thread and the folks paying us largely don't care and just want to see a working product. React in this analogy is a very quirky toolbox but it won because that toolbox helps people build the end product faster than most other toolboxes, even if it's filled with some questionable tools.
