how to check if internet connection is available in MacOS Terminal?

I used Ping command:

ping -c1 -W1 8.8.8.8

Works good if online, But in case of internet is't available or LAN is off the terminal takes long time to reply with result..

I want terminal reply in maximum time 1 or 0.5 second to use result in my

ExtendScript code:

var command = "ping -c1 -W1 8.8.8.8";

var result= system.callSystem(command);

I tried to set timeout using -t or -W but failed

Edit:

thanks to Philippe the solution is:
