I'm trying to get my head around Git branching and merging, but I'm feeling pretty lost. I have a basic understanding of Git commands like push, pull, and commit, but branches are a whole different ball game for me. I've watched videos and read articles, but nothing has clicked yet. Here are some specific questions I have: 1. When I create a branch, does it make a separate copy of the project files? 2. Why can't I create a branch directly in the remote repository? 3. Is it possible for others to keep making commits to the main branch while I'm working on a separate branch? 4. If yes, how do I pull in changes from the remote repository without merging my branch yet? I'd really appreciate any resources or projects, like those from The Odin Project, that could help me learn more about branches and merges. Thanks!

Think of branching as saving your place in time with the code. You can keep creating branches from the main branch as you want. It's actually pretty common for the main branch to get updates while you are working on your feature branch. When you want to incorporate those updates, you can switch back to the main branch, pull the latest changes, and then merge them into your feature branch. Doing this regularly helps avoid conflicts down the line!
Branches in Git are actually lightweight pointers to specific commits, not full copies of the files. So, you don't need to worry about using extra space when you create one. You can create a new branch on the remote repository by pushing a local branch to it. As for your main branch, yes, others can commit there while you're working on yours—you'll just need to merge their changes into your branch when you're ready. The typical approach here is to pull the latest changes from the remote and then merge them into your branch, ensuring you're up to date before merging your changes back to the main branch. If you want a deeper dive, the Pro Git Book is a great resource!
Thanks for the tips! I'll check out the Pro Git Book.
Creating a branch is more like labeling a specific commit rather than making a full copy of the project, so it saves space and keeps things organized. You can also create branches off of other branches! Just remember to update your branch with any changes from the main to avoid major merging conflicts later.
Great explanation, thanks! I'll try to pull updates more often.
