While working with TS in VS Code, I liked the intellisense of TypeScript + VSCode... it was able to piece itself together better than vanilla JS-- it predicted which objects, functions, or files I would reference quite well. So, I'll give it that.
I totally see a reason for it in the corporate realm of developer churn and in the vein of keeping projects very structured and stable. I might give it another go eventually.
For my own projects where I try to keep mental overhead low, and reduce focus on anything over than the main business logic, I prefer plain JS (e.g. within an ExpressJS or ReactJS project)
