I did a code experiment to solve a sort problem for a shoe store example by color, size, Etc. I hand wrote the HTML, the CSS Style and all the JS for the form and sorting 3 pages 30 items took me a half hour. Then using react? In 4 hours I still don't have the look or sort right.

A few years ago, react was sold to a project I was working on as an absolute necessity. The project was, briefly, four web pages with a little dynamic content. An afternoon’s work. Uncounted person-hours later, it never worked. I never understood how it was supposed to.
