Example text

The prototype model defines links between objects, instead of inheritance trees. The prototype model, as powerful as it is, is not very friendly to the average JavaScript programmer. 5 classes (if we choose not to use TypeScript exclusive features). To define a class in TypeScript, we use the class keyword: class Product {} Classes in TypeScript might have a constructor and methods just like JavaScript 2015. TypeScript also adds the ability to define class properties. price; } } In TypeScript, just like JavaScript 2015, inheritance is achieved through the extends keyword, and the super keyword is used to call the parent class when necessary.

Modules are a convenient way to gather a set of components, directives, services and pipes into a single entity that can into other modules. Each Angular application contains a single root module, in our case, AppModule. It contains the root component of the application. A module is simply a class decorated with @NgModule that accepts an object as a parameter, which defines the module metadata. Note that we use the dynamic bootstrapping approach leveraging the Just-in-Time compiler. This compiles components on the fly, in memory, and in the browser.

Components can optionally receive properties from the outside world and optionally communicate through callbacks or events. The business logic, structure and styling can be encapsulated inside the component code. Components in Angular 2 are just directives with a view. Actually, the component in Angular 2 is a type of directive. We can also write a directive that doesn't include a template (and will not be called component) in Angular 2. x. 0 we think of two kinds of directives: attribute directives that add behavior to the elements, and structural directives which we named: components.
