常见问题
- 和普通文本对比有什么不同？
- 文本对比会把换行、缩进、键的书写顺序都算作差异，噪音很大。这里是按数据结构逐字段比较，只报告真正的语义差异。
- 数组是怎么比较的？
- 按下标逐位比较。因此在数组中间插入一个元素，会导致后续所有位置都被判定为修改，这属于预期行为。
- 能对比很大的文件吗？
- 可以，但差异条目过多时表格渲染会变慢。建议先缩小到关注的子结构再做对比。

FAQ
- How is this different from text diff?
- Text diff treats newlines, indentation and key order as differences, producing huge noise. Here we compare field by field by data structure, reporting only real semantic diffs.
- How are arrays compared?
- Compared by index position. Inserting an element in the middle marks all later positions as changed — expected behavior.
- Can it compare very large files?
- Yes, but rendering slows when there are too many diff rows. Narrow to the relevant sub-structure first.
