This post explains our recent effort to improve JSON.stringify performance

This is super cool!
“By rethinking JSON.stringify from the ground up, from its high-level logic down to its core memory and character-handling operations, we've delivered a more than 2x performance improvement measured on the JetStream2 json-stringify-inspector benchmark. See the figure below for results on different platforms. These optimizations are available in V8 starting with version 13.8 (Chrome 138).”
