JavaScript is a scripting language. The term scripting language refers to programming languages that are executed by an interpreter from within a Web browser. An interpreter translates programming code into an executable format each time the program is run, one line at a time.
Programs written in scripting languages, such as JavaScript, are interpreted when a scripting engine loads an HTML page. A scripting engine is a interpreter that is part of a Web browser. A Web browser that contains a scripting engine to translate script is called a scripting host. Firefox and Internet Explorer are both examples of scripting hosts for JavaScript programs.
JavaScript is available in two formats: client-side JavaScript and server-side JavaScript. The standardized client-side JavaScript is the format available to HTML pages displayed in Web browsers (the client). Servers-side JavaScript is used with Web servers to access file systems, communicate with other applications, access database, and perform other tasks. Client-side and Server-side Javascript share the same basic programming features.
