Description
JavaScript is a universal scripting language that is both flexible and powerful. It is widely used as a scripting language for web browsers, it can create dynamic HTML content, and it is also used in the development of server-side applications on Node.js. The present course covers the main features of the language, traditional areas of its application and the various ways it is used in the development of web applications.The first part of the course covers in detail, the structure and syntax of the language, as well as its object model. The second part is dedicated to the DOM model of an HTML document. It also introduces CSS, and deals with DOM and CSS control using JavaScript. The course also covers event handling models, issues related to the creation of various forms, the XMLHttpRequest object, JSON and Ajax technologies, and provides an overview of the jQuery library.
