Yakov Fain talks with SE Radio's Matthew Farwell about the Angular web development framework. The show covers the philosophy behind Angular; who would want to use the framework; how an Angular application is composed, including how to handle form submission and validation; why Typescript was chosen for Angular; how Angular uses reactive programming (RxJS, in particular); how to test an Angular application; security concerns of web applications; who developed Angular and how it is supported, and performance considerations of an Angular application.
