How to Compare Code Snippets and Find Differences Instantly

Every developer has been there: you changed something, now it's broken, and you can't remember exactly what you touched. Or maybe you're reviewing a colleague's code and need to see exactly what changed between two iterations. This is where a Code Differ becomes indispensable.

The Power of Visual Diffs

Reading code line-by-line to find a missing semicolon or a changed variable name is tedious and error-prone. A visual diff tool highlights additions in green and deletions in red, making changes jump out at you.

Using the DevToolVault Code Differ

1. Paste Original Code

Copy the "before" version of your code into the left panel of our Code Differ.

2. Paste Modified Code

Copy the "after" version into the right panel.

3. View the Diff

The tool automatically computes the difference. You can switch between:

• Split View: Side-by-side comparison (great for understanding context).
• Unified View: All changes in one linear flow (great for quick scanning).

Why Not Just Use Git?

Git is powerful, but sometimes you just have two snippets on your clipboard, or you're comparing code from different sources (like a StackOverflow answer vs. your implementation). For these quick, ad-hoc comparisons, a browser-based tool is much faster than creating a temporary git repo.
