<!--
  Thanks for submitting a pull request!
  We appreciate you spending the time to work on these changes. Please provide enough information so that others can review your pull request. The three fields below are mandatory.

  Before submitting a pull request, please make sure the following is done:

  1. Fork [the repository](https://github.com/facebook/react) and create your branch from `main`.
  2. Run `yarn` in the repository root.
  3. If you've fixed a bug or added code that should be tested, add tests!
  4. Ensure the test suite passes (`yarn test`). Tip: `yarn test --watch TestName` is helpful in development.
  5. Run `yarn test --prod` to test in the production environment. It supports the same options as `yarn test`.
  6. If you need a debugger, run `yarn debug-test --watch TestName`, open `chrome://inspect`, and press "Inspect".
  7. Format your code with [prettier](https://github.com/prettier/prettier) (`yarn prettier`).
  8. Make sure your code lints (`yarn lint`). Tip: `yarn linc` to only check changed files.
  9. Run the [Flow](https://flowtype.org/) type checks (`yarn flow`).

## Summary
After comparing the README file Component-Based description with the description on the React website, I noticed the README file was missing the word "own". For design consistency I added the word.

## How did you test this change?
Since there was no change to the code and only the README file was modified, I ran no tests.

 React is a JavaScript library for building user interfaces.
 
 * **Declarative:** React makes it painless to create interactive UIs. Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes. Declarative views make your code more predictable, simpler to understand, and easier to debug.
-* **Component-Based:** Build encapsulated components that manage their state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
+* **Component-Based:** Build encapsulated components that manage their own state, then compose them to make complex UIs. Since component logic is written in JavaScript instead of templates, you can easily pass rich data through your app and keep the state out of the DOM.
 * **Learn Once, Write Anywhere:** We don't make assumptions about the rest of your technology stack, so you can develop new features in React without rewriting existing code. React can also render on the server using Node and power mobile apps using [React Native](https://reactnative.dev/).
