Also for me, the benefits of a statically typed language on a large team heavily outweighs not having TS in a chrome REPL. It's not even close. Maybe your use case is different, but for me it seems like you're missing the forest for the trees.
I mean yeah, sure, if you have to work on a large team in the browser/node you're going to have to make tradeoffs for that, and using TS seems like it'll help everyone go home at 5. I don't think I'm missing the forest for the trees, we're talking past each-other.
To illustrate a bit further, while I like Rust a lot, (the problems it tackles are MUCH more real than the ones TS does) and I put in the effort to learn and use it on a few personal projects I still find myself reaching for C almost universally these days. Even in the case of Rust's very useful tradeoffs I feel like they cost too much of my freedom, and TS' guarantees are much more surface level for a similar cost.
