Text differences: enhancing code and document quality

Tracking change is central to day-to-day development, collaboration and content creation. Diff (comparison) Technology originated in the Unix system, which uses algorithms to find the smallest collection of differences between the two files.

1. Specific issues addressed: subtle changes in human eyes that are difficult to identify

When a 500-long line of JSON The configuration document changes only one comma or one phrase in a legal provision, and eye examination is not only extremely time-consuming but also very easily omitted.

Code audit: Fast view changes before and after the merging branch, preventing introduction of Bug.
Version check: Compares the backup file with the current file to confirm whether it is synchronized.
Format clean-up: Check specific changes to code styles in automated format tools (e.g. Prettier).

2. Core algorithm: maximum public subseries (LCS)

Using classic differential algorithms, this tool aims to calculate the sequence of changes that best fit human logic. It not only recognizes additions and deletions in the row, but also supports fine comparisons of the line level in future updates.
