How do I disable console.log when I am not debugging? [duplicate]

I would probably abuse the short-circuiting nature of JavaScript’s logical AND operator and replace instances of:

console.log("Foo.");

With:

DEBUG && console.log("Foo.");

Assuming DEBUG is a global variable that evaluates to true if debugging is enabled.

This strategy avoids neutering console.log(), so you can still call it in release mode if you really have to (e.g. to trace an issue that doesn’t occur in debug mode).
