In my experience, the same enterprise developers will write complex abstractions in any language. If you have a million coders, 500k will by definition write below average code. And if some of them are elevated to tech leads in enterprise companies, they will spread their "style" to others.

This is definitely true... as a mod/admin on EchoJS, can't tell you the number of times I've seen unnecessary IoC/DI libraries created in JS/TS to match the style of Java or C#.

The reality is that as a scripted environment, there are provisions to override dependencies for testability.... so unless you literally need multiple implementations of a given adapter, you don't need a DI/IoC framework and adding one only detracts from your overall solution. I'm a strong believer in that abstractions should mostly serve to hide relative complexity to make the rest of the application easier to reason with.

I'm also a big fan of the first version of anything being done in a scripted language with an emphasis on correct behavior. JS/TS and Python are more adaptable earlier on without committing to Java/C# or even Rust or Go. I understand a desire for homogeny, but that often can hold you back from creating something functional and easy to replace first.
