Rodrigo Pombo: [0:05] Angular uses classes and decorators to define components. Inside the decorator, you'll define a selector and a template. You can use the selector inside any template. If you want to pass data to a child component, you can define an input and render it inside curly braces.
[0:19] To add event handlers, you use this syntax with parentheses and add the handler method to the class. You can add a state as class properties. Inside the curly braces in template, you can put any JavaScript expression and every time the state changes, Angular will re-render the component.

If you want to repeat something based on a list, you can use the entry for directive. You can also declare styles that only affect the elements within the component's template.
