JavaScript Using a while loop in a function counter which returns a string and then you have the console log that returned string by executing: console.log( counter(9) );

An buffer variable (generically, an accumulator) is going to be needed in the loop to 'build' the string so that after the work is done you can print the newly built string - since console.log() always adds a new line you have no choice.

Output:

console.log() I1
