-There are a couple of things to notice here. First, all views are wrapped in a Web Components `template` element. Second, did you notice the `\${heading}` syntax? Well, inside of a view, you have access to all the properties and methods of the class instance associated with that View and you can access them inside the content of any element or attribute by using the ${context.language.name} template sting syntax as shown above. The above syntax creates a one-way data-binding to the `heading` property. By "one-way" we mean that the dataflow is unidirectional and only changes to the `heading` property will affect the view. There is no "reverse" flow from the view back to the view-model.

 > Info: Presentation Patterns
 > We call a View's associated class its *View-Model* because it's a model for, or a model of the View. Most Aurelia development leverages the Model - View - View-Model pattern. However, Aurelia is flexible enough to enable also using patterns like Supervising Controller, Passive View and Model - View - Controller if desired.
