AngularJS Introduction

Duration: 3 Days

Overview:

AngularJS is the leading framework for building dynamic JavaScript applications that take advantage of the capabilities of modern browsers and devices. AngularJS, which is maintained by Google, brings the power of the Model-View-Controller (MVC) pattern to the client, providing the foundation for complex and rich web apps. It allows you to build applications that are smaller, faster, and with a lighter resource footprint than ever before.

Prerequisites:

Attendees should have some prior understanding of web development, HTML, AJAX, and JavaScript.
