Answer
map transforms items directly, flatMap flattens asynchronous sequences.
The map operator applies a synchronous transformation to each item, while flatMap is used for asynchronous operations where each input can lead to multiple outputs. Use map for one-to-one transformations, and flatMap for one-to-many.
