JavaScript ternary operator calling function or no-op

Question

What is best practice for debugging in JavaScript?

debugging ? console.log('info') : null;

My question is the null, what is standard practice for this in general, or in this debugging use case?

Answer 1

In your case:

debugging && console.log('info');

This trick is based on the "short circuit" feature and I suppose this info might be useful: http://en.wikipedia.org/wiki/Short-circuit_evaluation
