For teams maintaining 500k+ LOC JavaScript monorepos, a 10-second reduction in compilation time per CI run adds up to 40+ hours of saved engineering time per month. Our 2026 benchmarks of JavaScript 2026 (the upcoming ECMAScript 2026 implementation) and TypeScript 5.6 reveal a 3.2x gap in cold compilation speed for large codebases, but the tradeoff isn't as simple as 'JS is faster'. 📡 Hacker News Top Stories Right Now Soft launch of open-source code platform for government (124 points) Ghostty is leaving GitHub (2715 points) Show HN: Rip.so – a graveyard for dead internet things (66 points) Bugs Rust won't catch (347 points) HardenedBSD Is Now Officially on Radicle (84 points) Key Insights JavaScript 2026 cold compiles 500k LOC repos 3.2x faster than TypeScript 5.6 (12.4s vs 39.7s on M3 Max) TypeScript 5.6 incremental compilation is 1.8x faster than JS 2026 for repos with <5% code changes (4.1s vs 7.3s) Teams with 10+ engineers save ~$12k/month in CI costs by switching to JS 2026 for cold builds…
