What are the limitations of the map function in JavaScript?

The map function in JavaScript has several limitations, such as not modifying the original array, only working with arrays, and not being able to handle asynchronous operations directly.

Can you explain why it doesn't modify the original array?

The map function creates a new array populated with the results of calling a provided function on every element in the calling array, leaving the original array unchanged.

What happens if I use map on an object instead of an array?

The map function is specifically designed for arrays. If you try to use it on an object, it will return an error since objects do not have a map method.

Are there any alternatives to map for transforming objects?

Yes, for transforming objects, you can use methods like Object.keys(), Object.values(), or Object.entries() combined with array methods like map.

Can map handle asynchronous operations?

No, map does not handle asynchronous operations. You would need to use async/await with a loop or methods like Promise.all for that.
