Surely nobody would use javascript for either yea? The weaknesses of the language are amplified in constrained environments: low certainty, high memory pressure, high startup costs.
It's plenty usable. Most of the problems with the claude TUI stem from it being a TUI (no way to query the terminal emulator's displayed character grid), so you have to maintain your own state and try to keep them in sync, which more than a few TUIs will fail at at least sometimes, hence the popularity of conventions like Ctrl+L to redraw.
I think Bun helps with the memory pressure, granted this is relative to V8. I'd pushback on the certainty with the reality that TS provides a significant drop in entropy while benefiting from what is a sweet spot between massive corpus size and low barrier for typical problem/use-case complexity. You'll never have the fastest product with JS, but you will always have good speed to market and be able to move quickly.
