@darius I was given a react app to maintain at work. First thing I did was a full rewrite in standard Javascript. Went from a bloated, slow, ~500MB package on a nodeJS server to 3000 lines of standard Javascript that gets the job done in a fraction of the time and can run locally with no server required (although it is now served as static content by nodejs after getting evicted from Sharepoint). And I added a bunch of features in the process...
