Answer
flatMap transforms each element into a Flux and flattens the results.
The flatMap operator is used to asynchronously transform each element into a Flux and then merge the results into a single Flux. This is particularly useful when dealing with nested asynchronous operations. Consider an e-commerce scenario where each order in a Flux needs to be enriched with additional data from a web service; flatMap can help manage these asynchronous data fetches efficiently.
