Reading and writing from the DOM

JavaScript is a scripting language, not a general purpose programming language, and its world is the webpage that loaded it, not your operating system, not your hard drive. Instead, it has some great functions for grabbing and manipulating what's on the webpage. JavaScript is using something called the Document Object Model or the DOM to do this. Now, I can't talk much about the DOM without also talking a little bit about HTML and webpages in general. So while the next few minutes by itself is a little specialized to be something I'd call a general programming fundamental, well, that's not really about this.

It's the bigger picture here that's important. And the idea which is fundamental is that the languages you use become specialized to the world that they work in. So if you work designing mobile applications, well you'll end up being able to write code to deal with what happens if the phone rings while your program is running.
