How can I use the map function in more advanced ways?

The map function is a powerful tool for transforming data. Are you looking for specific examples or use cases?

Yes, I want to know how to use it with objects and nested arrays.

You can use map with objects by first converting them to an array of entries. For nested arrays, you can chain map calls.

Can you show me a code example for that?

Sure! For an array of objects, you can do something like this: array.map(obj => obj.property). For nested arrays, use array.map(innerArray => innerArray.map(item => item.property)).

That makes sense! What about using map with asynchronous functions?

For asynchronous functions, you can use Promise.all with map to handle the promises returned by the async calls.
