Client-side JavaScript & BOM

Web browsers can not only render HTML code styled with CSS, they can also execute JavaScript code. JavaScript is a really simple language that on its own can only be used for computations, so it does for example not contain any input/output functionality. But when our JavaScript code is executed by a web browser it will be executed in an environment where the web browser has added some extra goodies we can use. This environment is known as the Browser Object Model (BOM).
