Indeed. I would add as well that React (for me at least) went a long way towards erasing the difference between "backend" and "frontend" development. When I was a pup, they were very different things and a "frontend" developer meant basically someone who was really good at CSS and HTML and new all the magic incantations you had to do to create a nice UI with them. There were of course precursors such as AngularJS (and others) but React was really the first one for me where I could see frontend dev as just learning another framework the same as I would learn a backend framework.
