Introduction to JavaScript
So before we start writing some JavaScript, let's get some core concepts cleared up. It's very common to see JavaScript referred to as one of the three core languages of web pages. You have the HTML markup language for content and structure. What's your headline, how many divisions are in your page, how many paragraphs do you have, what are the contents of those paragraphs? Then the CSS, the style sheet language, for presentation. What font does the headline use, what's the background color of the page, what's the width of the div that the paragraphs are in? And JavaScript, the programming language for your behavior and interactivity.
