What's the difference between "Discard all changes" and "Stash all changes"?

I want to undo the command npm create vite@latest. I want to revert my changes without them showing up in git log or them being saved.

In Visual Studio Code's Source Control tab there are two buttons on top of unstaged changes, which appear when you hover over them:

On hover one says:

And the other reads:

What is the difference between them?

How can I replicate their behavior with the Git CLI?

• If you choose "Discard", your changes are gone and there will be no simple way of recovering them (see https://stackoverflow.com/questions/43541167/how-do-you-undo-discard-all-changes-in-vs-code-git).

  The corresponding Git command is something like

  git restore <file>
  

  or

  git checkout -- <file>
  

  e.g., you can use git restore . or git checkout -- . to discard everything.

  (There are several possible commands which have similar effects; see https://stackoverflow.com/questions/1146973/how-do-i-revert-all-local-changes-in-git-managed-project-to-previous-state)

• If you choose "Stash", your changes will temporarily be removed, but you will be able to recover them later (see e.g. https://stackoverflow.com/questions/20537223/what-is-the-intended-use-case-for-git-stash or https://git-scm.com/book/en/v2/Git-Tools-Stashing-and-Cleaning).

  The corresponding Git command is

  git stash
