The merge was successful because master had not changed since we made a commit on fencing. Git knew to simply update master with changes on fencing.
What would happen if you made a commit on master before you merged the two branches? Furthermore, what if the commit you made on master altered the same exact text you worked on in fencing? When you switch back to master and ask Git to merge the two branches, Git doesn’t know which changes you want to keep. This is called a merge conflict.
Instructions
You are on the master branch. In the code editor, where you have written:
Add the word “professional”, so the text reads:
Click Run.
Add resume.txt to the staging area.
Commit the changes to the repository with a commit message.
Imagine a few weeks have passed, and you’d like to develop your fencing resumé some more.
Switch back to the fencing branch.
From fencing, change the line so it reads:
Click Run.
Once again, add resume.txt to the staging area.
Commit the changes to the repository with a commit message.
