Question - What is Git bisect? How can you use it to determine the source of a (regression) bug?

Answer -

Git bisect is used to find the commit that introduced a bug by using binary search. The command for Git bisect is
git bisect
Now since you have mentioned the command above explain to them what this command will do.
This command uses a binary search algorithm to find which commit in your project’s history introduced a bug. You use it by first telling it a “bad” commit that is known to contain the bug, and a “good” commit that is known to be before the bug was introduced. Then Git bisect picks a commit between those two endpoints and asks you whether the selected commit is “good” or “bad”. It continues narrowing down the range until it finds the exact commit that introduced the change.
