is there some way of detecting using javascript that a user has switched to a different tab in the same browser window.
Additionally is there a way to detect a user has switched to a different window than the browser?
thank you

Modern websites use multiple "event listeners" and can detect every move the user is executing. So, if a user switches the tab or hovers over to another tab, it can gather the data and see whether the user stayed on the web page or not. A website can detect this anomaly by using cookies and IDs.
In the web page tab key works as an html element navigator, which means if you push the tab key button, it moves current element focus to the next element. This can be kind of hassle to the user of certain web based text editor, especially to the programmer.
Trap the window.onblur event.
It's raised whenever the current window (or tab) loses focus.

Most probably there is no standards javascript for this. Some browsers might support it but normally there is only a window.onblur event to find out the user has gone away from the current window.
