Diff Tools
Diff tools, also known as diffing utilities or file comparison software, are applications that compare the contents of files or directories to identify differences between them. They are commonly used in software development to track changes in source code, merge modifications, and review revisions. These tools typically highlight additions, deletions, and modifications in a visual or textual format, making it easier to understand changes over time.
Developers should learn and use diff tools when working with version control systems like Git, as they are essential for reviewing code changes, resolving merge conflicts, and ensuring code quality during collaborative projects. They are particularly useful in scenarios such as code reviews, debugging, and maintaining documentation, where identifying precise differences between file versions is critical for efficient workflow and error prevention.
