• JavaScript was created in 1995 by Netscape.
• It became popular very quickly and is now considered the language of the Web.
• The browser wars caused many problems for JavaScript and resulted in lots of frag-
mented and code that was hard to maintain.
• The advent of Ajax and its use in web apps such as Gmail and Google Maps promp-
ted a resurgence in JavaScript.

• Unobtrusive JavaScript is when the JavaScript functionality is separated from the
HTML content and CSS styling.
