Original Summary

I’ve been working on JSON Semantic Diff , an open-source tool for comparing JSON. The main problem I wanted to solve is that traditional diffs get really noisy when arrays of objects are reordered - even if the underlying records barely changed. Instead of comparing only by index, it tries to infer which objects are actually the same. That can be a simple key like id or sku , or even a composite like store + sku . If the match is ambiguous, it falls back to positional diffing instead of guessing, and you can manually choose the keys. It’s still early/alpha, but the core flow is working. Everything runs locally in the browser. Would love feedback, especially weird JSON examples that break the matching logic.

中文标题： 我正在构建一个尝试理解对象身份、而不仅是数组位置的 JSON diff 工具

作者开发了开源工具 JSON Semantic Diff，用于比较 JSON。它想解决传统 diff 在对象数组重排时产生大量噪声的问题：不只用索引比较，而是推断哪些对象实际相同，可用 id、sku 或 store+sku 等简单或复合键。匹配有歧义时会退回按位置 diff，而不强行猜测，也可手动选择键。目前仍处于早期/alpha，但核心流程可用，全部在浏览器本地运行。作者希望获得反馈，尤其是能破坏匹配逻辑的奇怪 JSON 示例。
