Imagine updating a page full of different forms like this one. Adding a new UI element or a new interaction would require carefully checking all existing code to make sure you haven't introduced a bug (for example, forgetting to show or hide something). + +React was built to solve this problem. + +In React, you don't directly manipulate the UI--meaning you don't enable, disable, show, or hide components directly. Instead, you **declare what you want to show,** and React figures out how to update the UI. Think of getting into a taxi and telling the driver where you want to go instead of telling them exactly where to turn. It's the driver's job to get you there, and they might even know some shortcuts you haven't considered! + + + +## Thinking about UI declaratively {/*thinking-about-ui-declaratively*/} + +You've seen how to implement a form imperatively above. To better understand how to think in React, you'll walk through reimplementing this UI in React below: + +1. **Identify** your component's different visual states +2. **Determine** what triggers those state changes +3. **Represent** the state in memory using `useState` +4. **Remove** any non-essential state variables +5. **Connect** the event handlers to set the state + +### Step 1: Identify your component's different visual states {/*step-1-identify-your-components-different-visual-states*/} + +In computer science, you may hear about a ["state machine"](https://en.wikipedia.org/wiki/Finite-state_machine) being in one of several “states”. If you work with a designer, you may have seen mockups for different "visual states". React stands at the intersection of design and computer science, so both of these ideas are sources of inspiration. + +First, you need to visualize all the different "states" of the UI the user might see: + +* **Empty**: Form has a disabled "Submit" button. +* **Typing**: Form has an enabled "Submit" button. +* **Submitting**: Form is completely disabled. Spinner is shown. +* **Success**: "Thank you" message is shown instead of a form. +* **Error**: Same as Typing state, but with an extra error message. + +Just like a designer, you'll want to "mock up" or create "mocks" for the different states before you add logic. For example, here is a mock for just the visual part of the form. This mock is controlled by a prop called `status` with a default value of `'empty'`: + + + +```js +export default function Form({ + status = 'empty' +}) { + if (status === 'success') { + return
