Although it is correct that MakeCode JS is still orders of magnitude slower than “regular” JS, you can still adjust your coding style and structure your program in a way to minimize the impact of expensive things such as function calls, property lookups, etc. My devlog post on [C3D](https://forum.makecode.com/t/unsignedarduinos-updates/46422/2) shows performance numbers and links to the repo, so you can check out the code. One day I plan on writing up a post on sim perf as well.
