 Due to the reactive nature of Vert.x, the API contains mostly asynchronous methods. They follow all a similar syntax:
 
 ```java

     // ...
 }

 Interesting here is the last parameter of the `doSomething` method. It is a function that will be used as a callback whenever the opertion succeeds or fails. Let's look at the example here:
 
 ```java

 The code reads a file as an asynchronous operation and invokes the callback when the file is read. The `Handler<AsyncResult<T>>` handles the file read and provides methods (`cause()`, `failed()`, `result()`) to compute the file read.
