json-eval-rs 0.0.88

# Node.js WASM Benchmark Example

A Node.js benchmark for JSON Eval RS using the WASM binding — mirroring the [C# FFI benchmark](../../../csharp-example).

## Overview

This example:
- **Parses** a schema and compiles it (measures parse time)
- **Evaluates** data against the schema (measures eval time)
- **Saves** results to the `samples/` directory
- **Compares** results against the baseline if `{scenario}-evaluated-compare.json` exists

## Usage

From the monorepo root (`bindings/web`):

```bash
yarn install
yarn workspace nodejs-benchmark start [scenario]
```

Or directly from this directory:

```bash
yarn install
yarn start [scenario]
# e.g.
yarn start zcc
yarn start zpp
```

**`scenario`** defaults to `zcc` if not provided. It must match a pair of files in `samples/`:
- `samples/{scenario}.json` — schema
- `samples/{scenario}-data.json` — input data

## Output

Results are written to `samples/`:
| File | Description |
|------|-------------|
| `{scenario}-evaluated-schema.json` | Full evaluated schema |
| `{scenario}-parsed-schema.json` | Parsed `$params` from the evaluated schema |
| `{scenario}-sorted-evaluations.json` | Same as evaluated schema (for comparison) |
