There is an abundance of poorly written react apps popping up everywhere.  Go to netflix and search for movies... the experience is terrible.  The search box lags typing by a long shot.  So much so its almost impossible to type in the full text of a movie name.  I&#x27;m sure there is the correct way to do this (not making the field a controlled component?) but the problem being there on such a major site is a sign that its hard to do react correctly.
