n.
Computer programming language developed by Netscape in 1995 for use in HTML pages.
JavaScript is a scripting language (or interpreted language), which is not as fast as compiled languages (such as Java or C++ ) but easier to learn and use. It is only loosely related to Java, and is not a true object-oriented language (see object-oriented programming ). JavaScript can be quickly added to a pure HTML page to provide dynamic features, such as automatically calculating the current date or activating an action. The JavaScript code must be interpreted and executed by a browser as it reads the Web page or by a Web server before it delivers the page to the browser.
