JavaScript tips for modifying browser tab titles_javascript tips

Modifying the title of tab or window is an older practice. Gmail uses it to prompt users for new chat messages. When a new page is loaded through AJAX, this site also uses it to update the tab title. How is this done? At that time, it was by setting the document object.

document.title = 'Hello!'; // New title :)
