What is a Diff Checker?
A diff checker is a tool that compares two pieces of text and identifies the differences between them. It is commonly used in software development to review code changes, compare configuration files, or verify edits to any text document.
The output uses a color-coded format: green lines indicate additions (present only in the modified text), red lines indicate removals (present only in the original), and unmarked lines are unchanged between the two versions.
