Just no man.

Yes, JavaScript has been the most popular language but it is exclusively because of the front-end. Many companies do not want to pay for separate back-end devs and ask their front-end devs to do it instead. These people (ab)use JS because they're most comfortable with it and are under crunch; so we end up with the abomination that is back-end JS.

It is NOT rivaling much lower-level languages; it can't even rival C#.

First off, it is interpreted. You are never going to be faster than competently written C, C++, Go, nor Rust. Secondly, the resources it takes to exist makes in a non-option for embedded machines - which Social-Security facilities are all but guaranteed to use.

Not to mention the horrendous (and insecure) package infrastructure, and under-powered core libraries - it would be the fullest extent disaster.

The saddest part? The larpers at DOG(shit)E are all but guaranteed to pick the worst tools for the job, over-engineer, and have extremely poor management. Meaning whatever they ship WILL collaspe the system day 1; and all of the people refusing to pay attention will be like "hOw CouLd THis HaPPen"
