Common Mistakes to Avoid

⚠️

Not normalizing line endings

Solution: Windows (\r\n) vs Unix (\n) line endings cause false differences. Normalize before comparing.

⚠️

Comparing minified vs formatted code

Solution: Format both files consistently first. Minified code will show 100% diff even if functionally identical.

⚠️

Ignoring context lines

Solution: Look at surrounding unchanged lines for context. A single change might affect meaning of nearby code.
