Frontend preview — no upload or external service.
Diff
Line 1: variable name changed from x to y. Line 2: initialization value changed from 1 to 2.
How the Code Snippet Version Diff works
- Paste both versions.
- Toggle whitespace handling. A diff full of changes that disappear when whitespace is ignored means a formatter ran, not that logic changed.
- Use the word-level view for single-line changes, where a line diff shows the whole line as changed for a one-character difference.
FAQ
Why ignore whitespace?
Because a formatting pass touches every line and buries the real changes. Ignoring whitespace shows the changes that alter behaviour, which is usually what you are looking for in a review.
What is a word-level diff?
A diff that highlights the changed characters within a line rather than marking the whole line. For a one-word change on a long line it is the difference between seeing the change and hunting for it.
Is my code uploaded?
No. Diffing happens in the browser, which matters when comparing proprietary code or anything containing configuration.
