Java Script

JavaScript can make your web site more dynamic.
A static web site is nice when you just want to show flat content, but a dynamic web site can react to events and allow user interaction.

JavaScript is the most popular scripting language on the internet and it works with all major browsers.

JavaScript is a programming language used to make web pages interactive. It is often used to update web pages after they have loaded in your browser.

JavaScript (JS) is a dynamic computer programming language.^[5] It is most commonly used as part of web browsers, whose implementations allow client-side scripts to interact with the user, control the browser, communicate asynchronously, and alter the document content that is displayed.^[5] It is also being used in server-side programming, game development and the creation of desktop and mobile applications.

JavaScript is a prototype-based scripting language with dynamic typing and has first-class functions. Its syntax was influenced by C. JavaScript copies many names and naming conventions from Java, but the two languages are otherwise unrelated and have very different semantics. The key design principles within JavaScript are taken from the Self andScheme programming languages.^[6] It is a multi-paradigm language, supporting object-oriented,^[7] imperative, and functional^[1][8] programming styles.
