Hello recently I come across a strange thing to me.
I declare a variable name with val and try to print it to the console the code look pretty much like this:

fun main() {
	val cup = 25
	println(cup + " cup of water")
}

However this snippet of code face a compile error and the way to work around this is as follow:

fun main() {
	val cup = 25
	println("" + cup + " cup of water")
}

I dont't know that in Java/Kotlin world this is normal or not but I think it's a little weird and can be improved to make a developer experience better (I come from JS field)

Probably you get an error because it's using Int.plus and passing a string to this function is not allowed. I would suggest using string templates instead:

val cup = 25
println("$cup cups of water")

"can be improved to make a developer experience better" → yep, that's what string templates are for 🙂

Thank you for the standard practice. 😄

You should have used string Template " $cup

You added a space in front that wasn't there. Why is this better than the one I suggested?
