 ### Don't Use HOCs Inside the render Method {#dont-use-hocs-inside-the-render-method}
 
-React's diffing algorithm (called reconciliation) uses component identity to determine whether it should update the existing subtree or throw it away and mount a new one. If the component returned from `render` is identical (`===`) to the component from the previous render, React recursively updates the subtree by diffing it with the new one. If they're not equal, the previous subtree is unmounted completely.

 The `defaultProps` will be used to ensure that `this.props.name` will have a value if it was not specified by the parent component. The `propTypes` typechecking happens after `defaultProps` are resolved, so typechecking will also apply to the `defaultProps`.
+
+### Function Components
+
+If you are using function components in your regular development, you may want to make some small changes to allow PropTypes to be proper applied.
+
+Let's say you have a component like this:
+
+```javascript
+export default function HelloWorldComponent({ name }) {
+  return (
+    <div>Hello, {name}</div>
+  )
+}
+```
+
+To add PropTypes, you may want to declare the component in a separate function before exporting, like this:
+
+```javascript
+function HelloWorldComponent({ name }) {
+  return (
+    <div>Hello, {name}</div>
+  )
+}
+
+export default HelloWorldComponent
+```
+
+Then, you can add PropTypes directly to the `HelloWorldComponent`:
+
+```javascript
+import PropTypes from 'prop-types'
+
+function HelloWorldComponent({ name }) {
+  return (
+    <div>Hello, {name}</div>
+  )
+}
+
+HelloWorldComponent.propTypes = {
+  name: PropTypes.string
+}
+
+export default HelloWorldComponent
+```

-In the React rendering lifecycle, the `value` attribute on form elements will override the value in the DOM. With an uncontrolled component, you often want React to specify the initial value, but leave subsequent updates uncontrolled. To handle this case, you can specify a `defaultValue` attribute instead of `value`. Changing the value of `defaultValue` attribute after a component has mounted will not cause any update of the value in the DOM.
