Tell us what’s happening:

Your code so far


function rangeOfNumbers(startNum, endNum) {
return [startNum,endNum];
};

You’re missing the key recursion logic in your code. You have to first test to make sure you’re not getting the same start and end number, and then call the function recursively to print the output.

function rangeOfNumbers(startNum, endNum) {
  return startNum === endNum // check for equality
    ?  [startNum] // equal, so just return the first number

    // not equal, so return the function passed with the
    // parameter options given
    :  [...rangeOfNumbers(startNum, endNum - 1), endNum ];
}

?[startnum]
:rangeOfNumbers(startNum-emdNum-1).concat(endNum);

In the recursive case you must call rangeOfNumbers with two arguments. You are calling it with one. Why is the .concat method there?
