# Add an interpolation to a component’s template

This tutorial lesson demonstrates how to add interpolation to Angular templates in order to display dynamic data in a template.

## What you'll learn

- Your app will display interpolated values in the `HousingLocationComponent` template.
- Your app will render a housing location data to the browser.

## Conceptual preview of interpolation

In this step you will display values (properties and `Input` values) in a template using interpolation.

Using the `{{ expression }}` in Angular templates, you can render values from properties, `Inputs` and valid JavaScript expressions.

For a more in depth explanation, please refer to the [Displaying values with interpolation](guide/templates/binding#render-dynamic-text-with-text-interpolation) guide.

<docs-step title="Update `HousingLocationComponent` template to include interpolated values">
This step adds new HTML structure and interpolated values in the `HousingLocationComponent` template.

In the code editor:

1.  Navigate to `src/app/housing-location/housing-location.component.ts`
1.  In the template property of the `@Component` decorator, replace the existing HTML markup with the following code:

        <docs-code header="Update HousingLocationComponent template" path="adev/src/content/tutorials/first-app/steps/08-ngFor/src/app/housing-location/housing-location.component.ts" visibleLines="[9,20]"/>

        In this updated template code you have used property binding to bind the `housingLocation.photo` to the `src` attribute. The `alt` attribute uses interpolation to give more context to the alt text of the image.

        You use interpolation to include the values for `name`, `city` and `state` of the `housingLocation` property.

    </docs-step>

<docs-step title="Confirm the changes render in the browser">
1.  Save all changes.
1.  Open the browser and confirm that the app renders the photo, city and state sample data.
    <img alt="browser frame of homes-app displaying logo, filter text input box, search button and the same housing location UI card" src="assets/images/tutorials/first-app/homes-app-lesson-07-step-2.png">
</docs-step>

</docs-workflow>

Summary: In this lesson, you added a new HTML structure and used Angular template syntax to render values in the `HousingLocation` template.

Now, you have two important skills:

- passing data to components
- Interpolating values into a template

With these skills, your app can now share data and display dynamic values in the browser. Great work so far.
