Within the component, we separate the UI into a view and the behavior into a class, with the appropriate properties and methods needed to support the behavior. If you are not familiar with classes, don't worry. We'll be discussing what they are in detail as we move through the example. Okay, so let's identify the UI and behavior that we will need for our application.

Then, inside the curly braces, we have four lines that declare the properties for our class. These are similar to ES5 variables, and we will use them to hold the values that we will need to run the application (you'll notice that these are the four values that we identified when we designed our component). What makes these properties different from standard JavaScript variables is that each property name is followed by : and number.
