Things to notice

Take a look through the source and note:

• The script tag that bootstraps the Angular environment.
• The text input form control which is bound to the greeting name text.
• There is no need for listener registration and event firing on change events.
• The implicit presence of the name variable which is in the root scope.
• The double curly brace {{markup}}, which binds the name variable to the greeting text.
• The concept of data binding, which reflects any changes to the input field in the greeting text.
