Day 11: Introduction to Git: Why Version Control is Critical | by Karthick Dk | Oct, 2024

Hey! So, today I want to talk about something that’s absolutely essential if you’re working on any coding project or even just writing documentation for your team — Git. I know version control might sound like some big technical jargon, but it’s actually super useful, and once you get the hang of it, you’ll wonder how you ever managed without it.

Let’s dive into why Git is so important and then look at a few real-world scenarios where it saves the day, plus some basic commands to get you started.

Git is a version control system (VCS), which means it helps you track changes in your code, files, or documents over time. Think of it like a “save game” for your projects. Every time you make changes, Git allows you to save snapshots of your work (called commits), so you can go back and see what’s changed or even roll back to a previous version if something goes wrong.

Without version control, you’d be manually copying files, renaming them like “final_version_v2.1” or “backup_before_changes” — and trust me, that gets messy, fast. Git keeps everything organized and helps teams (or even solo developers) collaborate smoothly.
