This can be useful in various scenarios, such as when you need to determine if an object contains binary data before performing certain operations like serialization or transmission over a network.

What are has-binary's main functionalities?

Check if an object contains binary data

This feature allows you to check if a given object contains any binary data. In this example, the object contains a Buffer, which is binary data, so the function returns true.
