1. Branching in Git

What is a Branch?

A branch in Git is a lightweight movable pointer to a commit. It allows you to work on new features, bug fixes, or experiments in isolation from the main codebase.

Why Use Branches?

To develop features or fixes without affecting the main branch.
To collaborate with others without interfering with each other’s work.
To organize work and manage releases.

Creating a Branch

You can create a new branch using:

git branch my-feature-branch

Or create and switch to a new branch in one step:

git checkout -b my-feature-branch

With newer versions of Git, you can also use:

git switch -c my-feature-branch

Switching Branches

To switch to an existing branch:

git checkout my-feature-branch

Or with the new command:

git switch my-feature-branch

Best Practices for Naming Branches

Use descriptive names, e.g., feature/login-page, bugfix/fix-header, docs/update-readme.
Use lowercase and hyphens to separate words.

Example Workflow

Create and switch to a new branch:
```
git checkout -b feature/add-login
```

Work on your changes and commit:

git add .
git commit -m "Add login feature"

Push your branch to GitHub:
```
git push origin feature/add-login
```

Summary Table

Action	Command Example
Create branch	`git branch my-feature-branch`
Create & switch branch	`git checkout -b my-feature-branch`
Switch branch	`git checkout my-feature-branch`
Push branch	`git push origin my-feature-branch`

Tip:
Always create a new branch for each feature or fix to keep your work organized and make collaboration
