Learning Angular

Learning Angular, Second Edition

A Hands-On Guide to Angular 2 and Angular 4






Learning Angular teaches modern application development with Angular 2 and Angular 4. It begins with the basics of Angular and the technologies and techniques used throughout the book, such as key features of TypeScript, newer ES6 syntax and concepts, and details about the tools needed to write professional Angular applications.
