Create a Flux emitting 1, 2, 3, 4, 5. Use the map operator to square each number, then subscribe and print each result on a new line.

The map() operator applies a synchronous transformation to each element.

Why this works

The map() operator transforms each element synchronously. Here we square each number. The lambda receives each element and returns the transformed value.

Expected output
