JavaScript is a scripting language widely used for client-side web development. It was the originating dialect of the ECMAScript standard. It is a dynamic, weakly typed, prototype-based language with first-class functions. JavaScript was influenced by many languages and was designed to look like Java, but be easier for non-programmers to work with.JavaScript is a scripting language widely used for client-side web development.

The languages name is the result of a co-marketing deal between Netscape and Sun, in exchange for Netscape bundling Suns Java runtime with their then-dominant browser. The key design principles within JavaScript are inherited from the Self and Scheme programming languages.<br><br>"JavaScript" is a trademark of Sun Microsystems.
