What is CI/CD?

CI/CD (continuous integration and continuous delivery) is an automated pipeline that checks and ships code. When a developer pushes a change, CI automatically runs tests and checks to catch problems, and CD automatically deploys the change if it passes. It makes releasing software faster, safer, and routine.

Continuous integration means changes are merged and tested frequently, so bugs are caught early instead of piling up. Continuous delivery means the tested code can be released at the push of a button, or automatically, rather than through a risky manual process.

The payoff is confidence and speed: teams ship small changes often, with automated checks guarding quality, instead of large scary releases. Setting up CI/CD is standard for professional teams and pays off in fewer production incidents.

What is automated testing?
Automated testing is code that checks your other code works correctly, run automatically instead of by hand. Tests confirm that features do what they should and keep doing so after changes. They catch bugs before users do and make it safe to change code without breaking things you forgot about.
What is the difference between Git and GitHub?
Git is the tool that tracks code changes on your computer. GitHub is an online service that hosts Git projects so teams can store, share, and collaborate on them in the cloud. Git is the technology, GitHub is a popular place to keep and work on Git projects. GitLab and Bitbucket are alternatives.
What is Git?
Git is the standard tool for tracking changes to code. It records every edit as a snapshot, so a team can work on the same project at once, see who changed what, and roll back to any earlier version. Almost every software project uses it. Working without it is like writing without an undo button.
What is version control, and why does it matter?
Version control is the practice of recording every change to a project over time, so you can see its history, work in parallel, and undo mistakes. Git is the dominant version-control system. It matters because it turns code from a fragile single copy into a safe, traceable, collaborative thing.
What is a package manager (npm, pip)?
A package manager installs and manages the outside code libraries a project depends on. npm handles JavaScript packages, pip handles Python, and most languages have one. Instead of manually downloading and updating libraries, you list what you need and the package manager fetches the right versions.
What is a code editor or IDE?
A code editor is the program developers write code in. A basic editor is a smart text editor for code. An IDE (integrated development environment) adds more: debugging, testing, and project tools in one place. Visual Studio Code is the most popular editor in 2026, and AI-assisted editors have become common.
