Will use of the debugging feature console.log reduce JavaScript execution performance? Will it affect the speed of script execution in production environments?

Of course, console.log() will reduce your program's performance since it takes computational time.

Is there an approach to disable console logs in production environments from a single configuration location?

Put this code at the beginning of your script to override the standard console.log function to an empty function.

console.log = function () { };
