Version lookups and comparisons scan and validate the same
versionsobject multiple times. The implementation now reuses validatedsonic-rsvalues to avoid these repeated scans. It preserves input validation and byte positions for JSON edits.Add benchmarks for version lookup, comparison, and mutation to CodSpeed. Make the metadata benchmarks compare the same fields, and remove the fixed speedup claim for
getMetaInfo().The table shows median latency in milliseconds from the second paired comparison. Both sides used the same fixtures and
tinybench@5.1.0. Both native binaries used release mode. The machine used an Apple M4 Max, macOSarm64, and Node.jsv24.22.0.Each
Packageoperation includes construction. Each mutation creates a newJSONBuilder. Speedup equals the previous latency divided by the new latency.getLatestVersion()diff()JSONBuilder.setIn()JSONBuilder.deleteIn()getMetaInfo()Across both paired comparisons, version lookup and comparison improve by 2.35–2.48× on these large fixtures, including construction. The gain depends on the operation;
getMetaInfo()remains approximately unchanged.Summary by CodeRabbit
