I've been working with php since 2001 and that whole time I've been cleaning up bad ruby and nodejs and PHP implementations and knowing JavaScript well enough to code in whatever front end nonsense comes out from PrototypeJS to jQuery to ExtJs to angular to react on and on ad nauseaum. Throughout PHP was my actual workhouse. It's kinda frustrating when I meet someone super into JavaScript as a backend because I still choose PHP even though I have 20 years of JavaScript under my belt and love Es2015+ promisable JavaScript.

I'm not even really sure why python is so popular for DevOps cause I do everything in php and it's unit tested and works well with reproducible results.
