+# JavaScript Benchmark
+
+This benchmark compares serialization and deserialization throughput in JavaScript for Apache Fory, Protocol Buffers, and JSON.
+
+It mirrors the benchmark layout used by [`benchmarks/cpp`](benchmarks/cpp/README.md) and uses the shared schema in [`benchmarks/proto/bench.proto`](benchmarks/proto/bench.proto).
+
+## Coverage
+
+- `Struct`
+- `Sample`
+- `MediaContent`
+- `StructList`
+- `SampleList`
+- `MediaContentList`
+
+For Fory, all struct schemas use explicit type IDs and field IDs so compatible-mode type metadata stays compact. The numeric type IDs match the C++ benchmark registration order.
+
+## Quick Start
+
+```bash
+cd benchmarks/javascript
+./run.sh
+```
+
+## Run Options
+
+```bash
+./run.sh --help
+
+Options:
+ --data
+ Filter benchmark by data type
+ --serializer
+ Filter benchmark by serializer
+ --duration Minimum time to run each benchmark
+```
+
+Examples:
+
+```bash
+./run.sh --data struct
+./run.sh --serializer fory
+./run.sh --data sample --serializer protobuf --duration 10
+```
+
+## Generated Artifacts
+
+Running the pipeline writes:
+
+- raw benchmark JSON to `benchmarks/javascript/benchmark_results.json`
+- plots to `docs/benchmarks/javascript/*.png`
+- Markdown report to `docs/benchmarks/javascript/README.md`
+
+## Notes
+
+- The benchmark builds the JavaScript package from `javascript/` before running.
+- Protobuf uses `protobufjs` with the shared `bench.proto` schema.
+- JSON results use UTF-8 byte length for serialized size.
