JavaScript is a more popular scripting language in Web pages. It is interpreted by the client browser and can be used in JSP, PHP, ASP and other Web sites.

JavaScript is an object-based and event-driven, interpretative scripting language with security performance and is widely used in Web applications. It does not need to be compiled, is embedded directly in the HTTP page, and transforms the static page into a dynamic page that supports user interaction and responds to application events. In Java Web programs, JavaScript is often used for data validation, browser control, and generation of clocks, calendars, and timestamp documents.

JavaScript can respond directly to the client's input in an event-driven manner without having to go through a server-side program. This means that JavaScript is event-driven.

The interaction between JavaScript and the Web page is accomplished by triggering related events by the user manipulating the browser page.

The DOM is the short name of the Document Object model, which is the application interface (API) that represents a document (such as an HTML document) and accesses and operates various elements that make up the document, such as HTML tags and text strings. It provides a separate, structured, object-oriented representation of the document, and allows access to the objects through their properties and methods.
