Then suppose you get a job that requires you to write React.
I had a job interview where the interviewer asked, "What framework would you install to accomplish x?"
My response was along the lines of, "I wouldn't use a framework. It's a simple problem, so you just write a function to do it. You don't need to throw yet another framework on the fire."
We had a brief discussion where he couldn't wrap his brain around the concept of just programming something, and not loading a bunch of frameworks to accomplish each task.
I didn't get the job. Later, I found out more about the company and realized that was a good thing.
