is there difference any performance between declaring the logger in companion object or just declaring it outside the class like this

private val logger = LoggerFactory.getLogger()
class SomeKotlinClass{
	//use logger here
}

? which one is for best practice?

Personally, I never try to analyze these kinds of functions performance-wise. It will never make that big of a difference

There is no real performance difference.

However, if you want your code more testable, I’d create a logger interface and use your favorite dependency injection method to provide an actual implementation.
