Sometimes, it's a price we have to pay if completely necessary. Indeed, it is frustrating how we can't have both readability and performance. Perhaps transpilers can be used to somehow convert less performant code to their more performant counterparts, but then that's just adding a whole new layer of complexity to the project. It isn't really a "solution" per se.
Transpilation seems like the cheapest of the three possible options to me.
Though, I don't see a lot of transpilation optimizing for performance.
I feel like we have the community for such an undertaking now, but those that care about raw performance of their web scripts have now focused on WASM instead. Which is a smart move, and has a lot more potential.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
