A scripting language developed by Netscape and used to create interactive Web sites.


JavaScript is a popular client-side scripting language because it is supported by both Microsoft Internet Explorer and Netscape Navigator, although there are differences in exactly how it is supported. This makes it important to test JavaScript code for cross-browser compatibility.

JavaScript code may be placed within each page or in a external file called by requested pages. External JavaScript files may be useful for code repeated on many pages, as it potentially saves download time and
prevents confusion by search engine spiders.
