In this exersise counter is beeing set to 1. I have to fill in a loop that stops at 11. Thats al ok. But the thing i dont understand ist that we "puts"counter on line 4. And after line 4 we set counter to counter= counter+1.

How is it possible that this get printed in the console while at the time the puts command was not given?

Line 4’s “puts counter” executes the variable already defined in Line 1 “counter = 1”.

The subsequent “counter = counter + 1” is applied to returns thereafter, incrementing each subsequent interation of “counter” by the value of “1”.

“counter = counter + 1” can also (instead) be written as “counter += 1” for the same result.
