Summary from the TLDR Dev newsletter

Bun won eight tests across 14 microbenchmarks on an M4 Mac (especially HTTP throughput and large JSON parsing), Deno won five (async scheduling and tight arithmetic), and Node won just one (small-buffer SHA-256 hashing). Node stayed competitive overall but didn't dominate anywhere.
