Exit from a node script

Snippet kitt decided around 22:19 on 5 July 2016 to publish this:

Node scripts wait for the last event before exiting. Use the global process object's exit method to exit cleanly.

Ends the process with the specified code. If omitted, exit uses the 'success' code 0.

Use a positive (read: non-zero) exit code to indicate error. 1 is reasonable. The shell that executed node should see the exit code as 1.

// default to 0, success
process.exit()  
 
// actual call
process.exit([code])
 
/* to exit with a 'failure' code: */
process.exit(1);
