In the form of a simple equation,
Git pull = Git fetch + Git merge
The git pull command is used to pull any newly made changes or commits to a target
branch in your local repository from a branch from the central repository.
The git fetch command has the same purpose as well. However, instead of storing
the new changes and commits in the target branch, it stores them in a new branch.
To ensure that the changes reflect in the target branch as well, we have to use the
git merge command.
The equation comes in handy in remembering the function of each command.
