Ask HN: Is all programming constantly changing or just front-end JavaScript?

I've been working on frontend dev for several years now, in the pre and post framework era. React and the other frameworks and ES6 in general, has meant a ton of change to the very basics of how we work. The way I do basic things has changed fundamentally in the last 4-5 years. Some of that is because I'm no longer a "beginner", but much is because things have just changed a ton. People who know the JS / frontend ecosystem AND backend stuff as well: Is this rate of change unique to JS, or is it everywhere? Is Rails very, very different now than 4-5 years ago? Django? I use PHP a bit and I've seen that change a bit, but it feels like mostly for the better, with namespaces in particular. Otherwise, I don't feel like PHP has had near the amt of change that JS has had. tl;dr: is it crazy everywhere or just with JS/frontend?
