“Now, I have a few requirements for this project. I want it to be fast, responsive, accessible, and mobile-friendly, so I’ll be using React.”
What is your definition of “fast” and “responsive”? I’ve written a number of web applications using web2py/Python and Beego/Go, and as far as I can tell, they’re plenty fast and responsive. What does React buy you?
I don’t know what you mean by “accessible”, but I can make my web applications “mobile-friendly” without too much difficulty.
Oh, and God forbid should you ever have to modify that boilerplate React configuration.
