The Browser Object Model

The part of JavaScript that does not have a standard is the Browser Object Model

We'll take a break from looking at Google Maps on Mondays for a while and instead look at the Browser Object Model. This is the part of JavaScript that handles interactions with the browser itself (and even beyond the browser in some cases). This is the most browser specific part of the JavaScript language because it doesn't have any recognised standards the way that the core and DOM parts of the language do. For the most part browsers have implemented the same things in their browser object model and where they haven't we can use feature sensing to work out which implementation the current browser uses. A lot of what the BOM does make available is not as useful as it might at first appear. though.
