when one or 2 words change in a long or dense line, it&#x27;s nice to have the specific changes highlighted<p>imagine a for loop in which a variable (used on every line) was renamed, and buried in the loop an assignment changed slightly (eg, + became -). with a standard diff, it&#x27;s really hard (for me) to pick up the minor change. with word by word diffs, it&#x27;s pretty easy<p>(i use netbeans diff, not this tool, but they appear similar)
