Sidecar on iPad extends your Mac’s desktop
The iPad's sidecar mode is the easiest way to actually get the second monitor I've never actually felt like buying. The only catch is that you need a modern MacBook or iPad, have your devices updated and use Apple's security preferred security standard.
Yes, not all Macs and iPads actually support Sidecar, which is kind of annoying. Here's the list of macOS and iPadOS devices that work with Sidecar.

Oh, and you also need to make sure your Apple ID is using 2-factor authentication, a security measure that requires you get a code that Apple sends to a secondary different device. Here's everything you need to know about Apple's two-factor authentication.
1. Make sure both of your devices have the same Apple ID logged in, and are on the same Wi-Fi network. Oh and re-start a device if you've just logged in.
2. Click the Apple icon.
4. Select System Preferences.
3. Select Sidecar
4. Select an iPad. Note, this is a great window to modify your preferences.
5. Use the Pencil for interacting with the Mac interface — you can't move windows or anything with your finger.
6. You can use your fingers, however, for tapping the TouchBar like interface.
You've now got a handle of merging your Mac and iPad.
