 That being said, the values _produced_ by getters can certainly change. In our case, the value produced by our `src` getter depends on the values of `lat`, `lng`, `width`, `height` and `zoom` from `this.args`. Whenever these _dependencies_ get updated, we would expect `{{this.src}}` from our template to be updated accordingly.
 
-Ember does this by automatically tracking any variables that were accessed while computing a getter's value. As long as the dependencies themselves are marked as `@tracked`, Ember knows exactly when to invalidate and re-render any templates that may potentially contain any "stale" and outdated getter values. This feature is also known as _[auto-track](../../../in-depth-topics/autotracking-in-depth/)_. All arguments that can be accessed from `this.args` (in other words, `this.args.*`) are implicitly marked as `@tracked` by the Glimmer component superclass. Since we inherited from that superclass, everything Just Works™.

@@ -379,7 +379,7 @@ When we use this syntax, we are passing a block—the `...some content here...`
 
 Inside of our block, we need to be able to access the current item _somehow_. The `{{#each}}` syntax provides the item to our block via the `as |item|` declaration, which creates a local variable `item`, also known as a _[block parameter](../../../components/looping-through-lists/)_. In other words, as we iterate through `@items`, we will have access to the current item that we're looping over through the block parameter (`item`) The block parameter is only accessible from within inside of the block. Ember will fill in the block parameter with the current item of the iteration, and it will do this each time that it renders our block.
 
-The need to provide some data to a block is not unique to the `{{#each}}` syntax. In this case, our `<Rentals::Filter>` component wants to take the unfiltered list of rental properties and match them against the user's query. Once the component has matched the rentals against the query, it will need to provide a filtered list of rental properties to its caller (the `<Rentals>` component).

 As it turns out, this ability to provide block params is not a superpower that only built-in syntaxes like `{{#each}}` can use. We can do this with our own components as well. In fact, Ember allows us to pass arbitrary data to blocks in the form of passing in additional arguments to the `{{yield}}` keyword. Indeed, this is exactly what we did with `{{yield this.results}}` in the `<RentalsFilter>` component.
