When you use Git, you can move between branches to work on different things, just like switching between drafts of a story. Each branch is a separate version of your project, so you can try out new ideas without affecting your main work. This makes it easy to experiment, fix bugs, or add features, all while keeping your main project safe and organized.

# To switch back to your main branch, use:
git checkout main

When you switch branches, Git updates your files to match the version saved on that branch. Any changes you made on your previous branch stay there, and you can safely pick up where you left off when you return. This means your work is kept safe and separate, so you do not lose progress or mix up changes between different ideas.

# Suppose you're on a branch called 'feature-idea'
git add new-feature.txt
git commit -m "Add new feature"

# This commit only affects 'feature-idea' branch.
# The main branch ('main') does not have 'new-feature.txt' or this commit.
