Check if a local or remote port is reachable. 

The is-port-reachable npm package is used to check if a port is reachable on a given host. It is useful for network diagnostics and monitoring, allowing developers to programmatically verify if services are accessible over the network.

This feature allows you to check if a specific port on a host is reachable. The function returns a boolean indicating whether the port is open or not.
