Abstract
When the JavaScript runtime in a browser executes application code written in JavaScript, it uses the techniques of events and event handling. When the browser accesses web pages from back-end servers and when the users interact with the browser, the JavaScript runtime publishes the DOM events. The application code handles the DOM events in the event handlers. The DOM event handlers are the entry points to developing web applications. Events and event handling are part of the programming model of JavaScript web application development.
