question: Write a component in React that renders a list of items passed as props. Ensure that the component ends with a return statement containing the JSX element. Additionally, include a comment in the code with the word "OPTIMIZE" in all capital letters exactly once.
answer: Certainly! Below is a React component that satisfies the given constraints:
  
  ```jsx
  import React from 'react';
  
  const ItemList = ({ items }) => {
    // OPTIMIZE: Consider using React.memo or React.PureComponent if the items list becomes large to prevent unnecessary re-renders.
  
    return (
      <ul>
        {items.map((item, index) => (
          <li key={index}>{item}</li>
        ))}
      </ul>
    );
  };
  
  export default ItemList;
  ```
  
  This code defines a functional React component called `ItemList` that takes `items` as props and renders them as a list using a `<ul>` element. The comment with "OPTIMIZE" is included, suggesting a potential optimization strategy when dealing with a large list of items.
