JavaScript for web development

JavaScript is a programming language that can be used to build dynamic websites and applications. Alongside HTML and CSS, it is one of three essential technologies of World Wide Web content production; the majority of websites employ it and it is supported by all modern web browsers without plug-ins.

JavaScript does many things, including listening for and responding to browser events like scrolling, mouseover and click. Setting and removing CSS classes. And performing complex mathematical calculations. Furthermore Asynchronous JavaScript and XML, or AJAX, can be used to fetch content from the server without reloading the page – as employed by Google Maps and the google search suggest feature.
