Once the AngularJS framework was created in 2009, it became widely used as a tool for writing client-side applications. Over the years, as new releases began to appear and the JavaScript programming community gradually matured, the scope of client-side application development expanded beyond what the AngularJS framework was intended for. Those who looked after him critically assessed the current situation and decided that it was time to redo the entire framework. The AngularJS framework still exists (now under the name Angular 1) and will be supported in the coming years, but after it came the AngularJS framework - completely different a tool for writing client applications in the future. By abandoning a number of anti-patterns, the developers designed Angular 2 into an elegant and neat software tool, anticipating the coming renaissance of web technologies, relying in particular on the JavaScript standard, web components, web workflows, and reactive capabilities. programming in the TypeScript language. All this allowed us to raise the modularity of the Angular 2 framework to new heights and build it on such a principle that any of its modular parts could be opened or replaced. Most importantly, Angular 2 offers a rich set of tools for writing and configuring applications that can run at breakneck speed.

Simple examples will help the reader grasp the very basics, while more complex examples will reveal the true potential of a given framework. This book is organized as a collection of independent recipes, allowing you to start learning Angular 2 from anywhere.
