How does the map() function differ from flatMap() in a Mono context?
Multiple choiceMediumchapter-19-curatedpremiumproject-reactorproject-reactor-mono
Answer and explanation
Correct answer
A. Map() transforms data; flatMap() transforms into another Mono.
Why
The map() function is used to transform the data within a Mono, while flatMap() transforms the data into another Mono. This allows for more complex asynchronous operations where additional Mono instances are generated.
