You were invited to two parties but they will happen at the same time! At party 1 your favorite band is playing and the other one is your best friend's birthday party.

You were invited to two parties! At one of them, your favorite band is playing - and the other one is your best friend's birthday party. Where should you go? No worries - as a time travel agent in training, you can go to both parties!
|
||||
|
||||
Where should you go? No worries - you are a time travel agent in training. You can go to both parties! To quickly switch between both events, check out the last commits and
|
||||
create branches with the `git branch [string]` command. Now you can easily switch between both branches by calling `git checkout [branch]`.
|
||||
To make it easier to tell which timeline is which, you can create time portals! (We call these "branches".)

You can use these little blue labels to give names to different timelines! This makes it easier to remember what happened where.
|
||||
|
||||
One of your colleagues messed up here - can you help reordering the branches correctly using the "reset" card?
|
||||
|
||||
When you do commits or merges while you're on a branch, the branch will grow with you. Try that while you eat that donut.
|
||||
|
||||
Finally, merge all timelines together, in a way so that the "main" branch points to the result. That's base reality!

Note that there are two options to "travel to the end of a timeline":
|
||||
|
||||
First, you can directly travel to the commit, like we've done it before.
|
||||
|
||||
And second, you can travel to the branch label. In this case, when you make a new commit, the branch will grow with you, and still point at the end of the timeline, which is usually what we want!
|
||||
|
||||
Let's try both of these!
