There are so many automated safe refactore and build time safeguards you can do with statically typed language, I’m much more comfortable making major changes and extension with Typescript than vanilla JS.

The problem with overengineering is that you don’t have a good grasp on a generalized architecture until you have two or three use cases. Of course anything dealing with cross cutting concerns like logging and authentication it’s easier to add up front.

I don’t know any modern front end frameworks, but when working within a team, I’m all for opinionated popular frameworks. It’s s lot easier to onboard people and from a completely selfish standpoint, developers who are concerned with their careers want to be able to put a transferable toolset on their resume.
