Introduction to SPAs with AngularJS
The document is an agenda for an introduction to single page applications (SPAs) using AngularJS. It begins with defining what an SPA is and then introduces AngularJS as a JavaScript framework for building SPAs. The agenda then covers setting up a first AngularJS project, using modules, controllers, directives, filters, routing, and services. It provides examples for each topic and emphasizes concepts like two-way data binding, dependency injection, and using AngularJS features to interact with REST APIs.
