Yeah or even simple typos, or mixing up the order of arguments, are things that are hard to catch in regular JS (except at runtime) but trivial in TS.

I suspect a lot of people might have had bad experiences with codebases which overuse complex types or trying to type things like Redux which is messy. When I use TS for personal stuff I’ll typically be a bit loose about things like any in places where I don’t care (for now) and I feel it doesn’t add much overhead, but I have been using it for a long time so it’s become second nature.
