The Svelte implementation is very inefficient. With a small change I was able to get it to the number two spot on both duration and memory, at least running on this machine. Thyn is in the top spot on both counts — not _hugely_ surprising for a brand new project, but impressive nonetheless.

React, needless to say, languishes at the bottom.

Will send a PR to fix the Svelte implementation.

Thanks for the PRs. Will update it soon.
