     -   Example: `document.body.classList.toggle( 'has-focus', nodeRef.current?.contains( document.activeElement ) );` may wrongly _add_ the class, since [the second argument is optional](https://developer.mozilla.org/en-US/docs/Web/API/DOMTokenList/toggle). If `undefined` is passed, it would not unset the class as it would when `false` is passed.
     -   Example: `<input value={ state.selected?.value.trim() } />` may inadvertently cause warnings in React by toggling between [controlled and uncontrolled inputs](https://reactjs.org/docs/uncontrolled-components.html). This is an easy trap to fall into when eagerly assuming that a result of `trim()` will always return a string value, overlooking the fact the optional chaining may have caused evaluation to abort earlier with a value of `undefined`.
 
-### `@wordpress/element` (React) Components

 It is preferred to implement all components as [function components](https://reactjs.org/docs/components-and-props.html), using [hooks](https://reactjs.org/docs/hooks-reference.html) to manage component state and lifecycle. With the exception of [error boundaries](https://reactjs.org/docs/error-boundaries.html), you should never encounter a situation where you must use a class component. Note that the [WordPress guidance on Code Refactoring](https://make.wordpress.org/core/handbook/contribute/code-refactoring/) applies here: There needn't be a concentrated effort to update class components in bulk. Instead, consider it as a good refactoring opportunity in combination with some other change.
