Overview
Angular (sometimes called Angular 2 or 2+ even though it is currently on version 17) is a complete redesign of its predecessor, AngularJS. It aims to bring forward the best features of the original whilst correcting or replacing its flaws. This version of Angular is based around a strongly typed language (TypeScript), adopts a component-based architecture and provides fine-grained control over the type and extent of data binding performed.
This course introduces all the features of Angular via sample applications of increasing complexity. It will enable experienced client side developers to immediately begin creating Single Page Applications that interact with RESTful services. As the course progresses, the official Angular Style Guide will be continually referenced, and there will be a strong focus on writing unit and integration tests alongside the components and applications.
