Git
Tracking and coordinating changes to code across teams and time
Git is a distributed version control system that records every change made to a codebase as a named, reversible commit. Developers use it to work on separate branches simultaneously, merge contributions from multiple people, and roll back to any previous state when problems arise. Unlike centralised version control systems, every Git repository holds a complete copy of the project history, meaning teams can work offline and collaborate without a single point of failure. Git is the near-universal standard for source control across software development and is a baseline expectation for any role that involves writing, reviewing, or deploying code.

- Tracking every change to a codebase over time, recording the author, timestamp, and purpose of each modification
- Managing parallel development streams through feature branches that can be reviewed, tested, and merged independently of each other
- Reviewing proposed changes via pull requests before they are merged, allowing teams to catch errors and share knowledge
- Recovering any previous version of a file or entire project state when a change introduces a regression or problem
- Coordinating contributions from multiple developers working simultaneously on the same codebase, resolving conflicts when they arise
Git Learning Resources
The official Pro Git book, available free at git-scm.com, is the definitive reference covering everything from first commits to advanced internals. For hands-on practice, Learn Git Branching at learngitbranching.js.org builds the mental model interactively without any local setup.
