I'll add one more perspective: git is the "right" way to do it, but I'm a lazy forgetful person who wants to work on the laptop but the changes on the desktop aren't committed or pushed remote. What I often do is to use VScode's remote development tools to open a remote connection the last computer with uncommitted changes, and work like that. If I'm headed out, I'll use the remote connection to commit the code so I can access it off my home network via codeberg.org.

Occasionally if I'm already out, I've even used "raspberry pi connect" to remote onto my network, then ssh over to my desktop, then commit and push. Don't do that though. That'd be irresponsible.
