What are iterable methods in React?

Iterable methods in React refer to functions that can be used to iterate over collections, like arrays or objects, often used in rendering lists.

Can you give me examples of these methods?

Sure! Common iterable methods include map(), filter(), and forEach(), which help manipulate and render data.

How do I use the map() method in a React component?

You can use map() to transform an array into a list of JSX elements. For example: array.map(item => <Component key={item.id} data={item} />).

Are there any performance considerations when using these methods?

Yes, using methods like map() can impact performance if not used correctly, especially with large datasets. Always ensure to use keys for list items.
