To me the language is very secondary to me as it exists in an endless swamp of:

- chaotic and baroque layers of tooling that need to be figured out and made to keep working

- a software tradition where poorly thought out ideas are implemented with vigor resulting in design by accident

- ...which then results in frequent rewrites

- a universe of low quality libraries and frameworks resulting in frequent discovery of serious bugs

- every project having lots and lots of dependencies

And that's before we even consider the language or the congenital defects inherited from JavaScript.
