Question

What is the command used for debugging output in Node?

(a) print();

(b) console.log(…);

(c) debug(…);

(d) execute(…);

I had been asked this question during an interview for a job.

My doubt is from Asynchronous I/O with Rhino topic in chapter Server-Side and Client-Side Scripting of JavaScript

Answer 1

The correct answer is (b) console.log(…);

Explanation: Console.log() prints the content in the argument on to the output screen. Node defines console.log() for debugging output like browsers do.
