So, remove the majority of dynamic websites from the internet, basically? I don’t see how that’s helpful. I get you’re (probably) being hyperbolic, but the fact remains that it’s a highly useful language for generating dynamic web content.

I was refactoring yesterday some JS code, bad JS code it is worse then bad PHP code, so by your logic JS has to go too and probably many other languages.

Good code uses small functions that do a simple thing, then you combine those functions , it will look similar for most programming languages

Let's smite the vast majority of web content due to technical purity?

Why are web engineers snobs? Get the job done and move on.
