JavaScript Programming

JavaScript is one of the three core programming languages web developers should know, it programs the behavior of web pages giving your users a rich and responsive experience. JavaScript is at the core of the full stack web development and helps you progress your career as a Full Stack MEAN/MERN web development tracks. JavaScript is a scripting language that enables you to create dynamically updating content, control multimedia, animate images, and pretty much everything else.

In summary, JavaScript is a programming language that drives the web: from front-end user interface design, to backend server-side programming, you'll find JavaScript at every stage of a web site and web application. It allows you to implement complex features on web pages - every time a web page does more than just sit there and display static information for you to look at - displaying timely content updates, interactive maps, animated 2D/3D graphics, scrolling video jukeboxes, etc. - you can be sure that JavaScript is probably involved. It is the third layer of the layer cake of standard web technologies, the other two being HTML and CSS.

In simplest terms, JavaScript is the Programming Language for the Web. JavaScript can update and change both HTML and CSS. It can calculate, manipulate and validate data. JavaScript can be used to create special effects such as rollover images and pop-up windows and is also useful for analysis tasks like browser checking or form validation.

Uplatz provides this comprehensive JavaScript course with end-to-end demonstration of concepts starting from the most fundamental to the most advanced features of JavaScript. This course also includes the a full session (with free downloadable booklet) on the most important JavaScript interview questions and answers. Additionally, this JavaScript training provides you a comprehensive session on logical reasoning problems & solutions in JavaScript, again with a freely downloadable booklet of the session.

This JavaScript training will empower you with the skills to design client-side, platform-independent solutions that greatly increase the value of your Web site by providing interactivity and interest. You will learn how to use JavaScript to communicate with users, modify the Document Object Model (DOM), control program flow, validate forms, animate images, create cookies, change HTML on the fly, and communicate with databases.

The first phase of this JavaScript course focuses on essential JavaScript principles and techniques, including common programming practices, working with variables and data, and using functions, methods and events. This JavaScript course by Uplatz will familiarize you with programming basics such as writing program instructions that work with variables, numbers and text, adding comments to your code, gathering input from a user and giving a response, creating simple dialog boxes that prompt the users, etc.

The next part of the JavaScript course then focuses on intermediate JavaScript programming techniques that will build upon your knowledge and present solutions for more functional and exciting Web pages. These include using control structures for program flow, manipulating the JavaScript DOM, using language objects, creating expressions, and creating and using custom objects.

Finally you will learn how to apply JavaScript programming techniques to develop interactive forms, change HTML dynamically, create and use cookies, and explore security issues related to JavaScript. You will also take a deep-dive into how to build extensions to the JavaScript language, including JavaScript code libraries, Web APIs and advanced interactive Web applications with AJAX. You will also learn throughout the course the tools and techniques for debugging and troubleshooting your JavaScript code. The JavaScript training will familiarize you to Frames, Cookies in JavaScript, working with Objects and Methods, and embedding JavaScript within HTML.

By the end of this JavaScript course, you will be able to understand the core concepts and programming constructs on JavaScript and be able to use JavaScript to build complex web applications.
