jаvascript is a powerful scripting language that every web developer should be familiar with. jаvascript has brought in many changes to the web development field. It has provided web developers with a way of making web pages more interactive. This is something most web visitors look for. If you know of validations, like checking whether a user enters correct details when filling forms, jаvascript is the best language to use for the implementation of such. It is one of the technologies of the WWW (World Wide Web). The good think with jаvascript is that it is supported by all modern web browsers. This means that you are not expected to get any special plugins to be able to run its scripts.

This book assumes that we already know how to use HTML to specify web page structure and content. It will be additionally beneficial if we are familiar how pages are styled with CSS, separate from the web page structure. If this is the case then we are ready to add a little behavior to the page and make it more dynamic and interactive with jаvascript. Otherwise, without HTML and CSS, jаvascript will not do us much good. They are viewed as the three fundamental pillars of the web page: structure, presentation and behavior.

Scripting languages, like jаvascript, are note compiled, but rather are interpreted on-the-fly. This means that no special software is involved as the user's own browser runs and executes the code as it is encountered.
