Yea there's certainly a lot of mixed opinions and learning curves involved to be sure. On the one hand, I love how many options there are to build web applications, but on the other, it really does feel fragmented and hiring front-end engineers is a huge gamble with all the different preferences involved because there is no true concept of "standards" everyone follows.

Thankfully it's pretty easy to align a team with a little time and learning what everyone wants.
