Refresh list of Online User for certain interval with MySql

lets figure that I want to make a social web media like facebook which user can create and log in with their account. The user can see in a navigation bar which friends are online and offline.

Is there a way to update online and offline users without refreshing the page for a certain interval such as every 10 minute it will query data from database and update the data ???

Thanks :D

You can establish a function in JavaScript that will be performed on a particular interval. In this function, you can do an AJAX server request that will fetch the desired data and update only those fields on the page where the data are being displayed.

There are courses here covering:

I believe these are both parts of the Full Stack JavaScript track.
