What is text comparison and why is it essential?
Text comparison (also called diff or text differencing) is the process of analyzing two versions of text to identify differences, additions, and deletions. This essential tool for version control, content editing, and quality assurance uses advanced algorithms to highlight changes visually, making it easier to review document revisions, track code changes, and ensure content accuracy. Modern diff tools use color-coded highlighting to show exactly what changed between versions. Learn more about text comparison algorithms and version control systems.
