问题
I'm learning Git and reading the Pro Git book. The term "branch tip" is used sometimes in the book and also here on Stack Overflow, but I can't find the meaning of it.
回答1:
A branch tip is the last commit or most recent commit on a branch. Basically it points to the most up to date code in the branch.
回答2:
Using an image from the Pro Git book to illustrate:
master, hotfix and iss53 are all "branch tips" here. Kevin's answer is correct, but this might be easier to understand for beginners.
