Earlier quoted context omitted.
So? Are you implying I should have switched to react 13 years ago, when it was just another framework who come and go? And then my experience would have been stable? (I kind of doubt it, when my unstable web experience was caused by changes into how canvas works, webrtc, indexeddb, webgl, webgpu. I don't make simple UI's) Or well, just that "let" was introduced makes all my beautiful old code with only "var" bad code…
"let" is 11 years old. My point is that the web is not really an unstable platform anymore, it's just something people say that used to be true. Also using var and other superceded constructions doesn't make the code bad; that's not what bad code is. I think you know this.
My main metric is, if it is readable. So yes, I also don't consider my old code with var bad. But other people do.
