Sure, but when we have tech 20 years old we can assume you don't need two days to learn it. 7 years is not that young but it changes way, way too fast. So the react 7 years ago is not the same as today: hell I have nodejs and react stuff that simply doesn't work anymore and is only a few years old. While php/html/css/jquery code written 15+ years ago is fast and robust on the very latest versions. I updated one of my oldest saas app written 17 years ago to the latest php version from apache to nginx and the latest php and it works 100%. That makes me sleep well at night. It has 60000 active users and costs $4/mo to host and has not had downtime in over 10 years. How is this new stuff holding up?
