What is the difference between “git reset --hard” and “git checkout .”?

Question

When I want some changes in my project and I want to return to the state of the last commit, I can use these both options. Do they actually do the same thing or is there any

Answer 1

git checkout get update data from Git server, also keep your change at local machine.

git reset --hard make a copy identity like Git server at a specific HEAD, and discard all change at your local machine.
