We can bind to object properties, just remember that everything will be interpolated as a string. '} } } What we write between the curly braces is an angular expression. It means that angular evaluates the expression before it is converted into a string. In other words, we can put simple logic in our expressions and even bind to a method. lastName}`; } } Inside angular expressions we can't use the new keyword and operators such as: ++, --, and +=. As a rule of thumb, expressions shouldn't be complex.
They should be able to render dynamic data, respond to user interactions, and react to events. In this chapter, we will continue where we stopped in Chapter 4, Building a Basic Component, focusing on the component template syntax, and learn how to bind data and events. The topics that will be covered are as follows: Data interpolationUsing core directivesProperties bindingEvents bindingsTwo-way bindings Data interpolation In Chapter 3, The TypeScript Primer, we bound a simple string to the template.
Components can be composed together to create a complex user interface. 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.
