Glad you enjoy large javascript projects and it works well for you.

Architecture is important regardless of what language you are using.

Thanks. I feel like there should be a lot less discussion about tools and a lot more discussion about architecture. I find that with good architecture, the language doesn't really matter at all.

I've built high quality very complex projects in both JavaScript and TypeScript (both alone and as a team lead). My point is that I (and people of my skill level) can complete the project/subproject much faster with JavaScript so it gives me a lot more extra time to write tests.

Yes, architecture is important, but you can't architecture away neither errors nor domain complexity.

Besides, your language is the largest constrain you'll have on your program architecture.
