Well, probably the biggest difference is npm... A great package manager makes things easier to create and use as independent modules. PHP has frameworks, but these are a bit cumbersome.

JavaScript even with the bad parts is still more consistent and friendly to use than the core methods within PHP, inconsistent naming structures, parameter ordering and a lot of other issues at the language level.

I've NEVER liked PHP as a language... and that stems from VERY early on in web development. I've used a number of platforms and languages over the years, and none have irked me nearly as much as PHP has.
