The Confusion πŸ˜•β€‹

Backend Dev: "I just successfully rebased my backend branch onto main with 18 commits. So now my main branch has all my backend changes, right?"

Git Mentor: "Actually... no! Your backend branch is updated, but main still doesn't have your changes!"

Backend Dev: "WHAT?! But I thought rebase puts my commits on top of main? Isn't that the same thing?"

My frontend mentor explained the beautiful double nature of async/await: it makes code look synchronous inside the function but stay asynchronous to the outside world. This conversation finally made async/await click for me.
