✌️ How V8 is Making JSON.stringify More Than Twice as Fast The V8 team has made JSON.stringify over twice as fast, giving your apps an automatic performance boost for common tasks like API responses and caching, at least once Node upgrades to V8 13.8 (Node 24 uses V8 13.6). This article unpacks the low-level work behind the speedup. Patrick Thier (V8)
