How to properly uninstall and reinstall The Sims 4?

Normally, you can simply uninstall Sims 4 through Origin, but if you're formatting your laptop, you don't even need to do that much, since the process will safely erase everything.  If you want to keep your saves and other user content, put aside the Sims 4 folder in Documents >Electronic Arts, as in, save it on an external drive or USB stick, or zip it and upload it to cloud storage.
