How do I use iterators in React?

You can use iterators in React to efficiently render lists of elements. Would you like an example?

Yes, please provide an example of using iterators.

Sure! You can use the map() function to iterate over an array and return a list of components. For instance:

const items = ['Apple', 'Banana', 'Cherry'];

const ItemList = () => (
  <ul>
    {items.map(item => <li key={item}>{item}</li>)}
  </ul>
);

This will render a list of fruits.

What if I need to use a more complex data structure?

For complex data structures, you can still use map(), but you might need to destructure the objects. For example:

const users = [{id: 1, name: 'Alice'}, {id: 2, name: 'Bob'}];

const UserList = () => (
  <ul>
    {users.map(({id, name}) => <li key={id}>{name}</li>)}
  </ul>
);

This will render a list of user names.
