You can use SessionStorage for that! SessionStorage is not cleared when the page is reloaded but when it is closed. So basically you could set a key/value pair when the page is loaded, but before that you check if the key/value pair exists. If it does exists it means that the page was reloaded, if not it means that the user opened the page for the first time or in a new tab.

if (sessionStorage.getItem('reloaded') != null) {
    console.log('page was reloaded');
} else {
    console.log('page was not reloaded');
}

sessionStorage.setItem('reloaded', 'yes');

This way you can doStuff() with the onunload event (user leaves the page), and otherStuff() if the key/value pair is set (user reloaded the page).
