Git and GitHub: where to start and why every developer needs them

If you start your journey in programming, sooner or later you will come across mysterious words Git and GitHub. It seems like these are some scary things for "pros" - but in fact these are your best friends already from of the first project.

Git is a version control system. GitHub is a place where you can store and share your code.

Let's figure out how everything works and why no developer can do without it today.

What is Git and why do you need it

Imagine that you wrote the perfect code, and then decided to change something... And everything broke. Git allows undo changes, compare versions and work in a teamwithout disturbing each other.

Git is like a time machine for code. Each commit is a "snapshot" of your project at a certain point in time.

git init       # create a repository
git add .      # adding all files
git commit -m "First commit"  # saving the state

What is GitHub and how is it related to Git

GitHub is a cloud home for your repositories. It stores all your projects online and allows others to see your code, comment and help.

• show your projects to employers;

• work in a team;

• store backups and not lose the code.

How to start using Git and GitHub

1. Install Git from the official website.

2. Create an account on github.com.

3. Link a local project to GitHub:

git remote add origin https:// github.com/your_name/your_project.git
git push -u origin main

Now your code lives in the cloud — and you can work with it from any device.

Teamwork: branches and pull requests

Branches allow you to work on different functions in parallel. For example, you have a branch main and you create a new one — feature-login.

When you finish your work, you can send a Pull Request so that your colleagues can see the changes and approve them. This is the magic of GitHub — collaborative development without conflicts and chaos.

Why you should master Git as early as possible

• Even if you work alone, Git will save you from data loss.

• You can find thousands of ready-made libraries and code on GitHub.

• Employers almost always ask: "Drop the link to GitHub."

By mastering Git and GitHub, you are already taking your first professional step into the world of development.

In Codice everything is interactive, with real projects and code verification right in the browser.
