-# Step 1-06 Demo: Creating a State-Driven UI
+# Step 1.6 - Creating a state-driven UI (Demo)
 
 In React, the data travels in one direction: top-down in the form of state propagating down the component hierarchy. Only the component containing the state can change the state itself. When a UI interaction occurs, a stateful component must pass down an event handler to the UI component triggering the event in order to signal a state change.
 
 [Step #3 of "Thinking in React"](https://reactjs.org/docs/thinking-in-react.html) suggests finding the "minimal set of mutable state" that your application requires. So in this demo we are going to add that "minimal state" to our application and drive our UI off of that data. With that done, the next step will be to create ways to modify that state, which will in turn cascade down through our UI. This [reconciliation](https://reactjs.org/docs/reconciliation.html) process, figuring out what in your UI needs to change based on changing state, is what React excels at.
 
-## Adding State to `TodoApp.tsx`
+## Adding state to TodoApp
 
-Inside our `TodoApp` class, we will add the minimal state for our application, which includes just two keys: `todos` and `filter`. We don't need to worry about a `remaining` value because it can be calculated by counting the number of todos where the `completed` field is set to `false`.

 ## Intro to TypeScript
 
-Taking a look at our components in `TodoApp`, you can see that our list of props is not just getting longer, but is getting much more complex! We're passing through functions with various signatures, complex `todos` objects, and filter strings which are always one of three values.

-As applications grow, it becomes increasing difficult to remember what each function does, or what each todo contains. Also, as JavaScript is a dynamically typed language, if I wanted to change the value of `todos` to an array inside my `TodoList`, JavaScript wouldn't care. But if `TodoListItems` was expecting an object, our application would break.

-If you've ever used [Sass](https://sass-lang.com/) you are familiar with this concept. In the same way that all valid CSS is valid Sass, all valid JavaScript is valid TypeScript. That's why most of these exercises have been written in `ts` and `tsx` files instead of `js` and `jsx` files.

There isn't any interactive UI in this component, as we're simply passing `completed` down to each `TodoListItem`, but we can write a props interface for the component to make sure that everything gets passed down properly.
