Composing Asynchronous Operations

Futures help us run tasks without blocking the main program. But what if one task's result is needed for another, or we need to combine results from multiple tasks?

This is where composing Futures comes in handy. We'll learn how to chain and combine these asynchronous operations, making your Scala code more powerful and responsive.

The map method is used when you have a Future and you want to transform its successful result into another value. The transformation function you provide will be applied once the Future completes successfully.

• It always returns a new Future.
• It's perfect for simple, synchronous transformations on an asynchronous result.
