Build a Pyramid Generator - Build a Pyramid Generator

Tell us what’s happening:

Hopefully this is ok to ask here, I realized after getting this far I should be adding in “\n” instead of having the function console.log the rows separately so I’m going to have to start over regardless, but this function works for the “true” condition except the last line or two (depending on # of rows) reads “undefined” - can anyone help me understand what’s happening in the last iteration or two? I appreciate any input!

Your code so far

function pyramid (unitPattern, numOfRows, isPointingDown) {
  let numOfUnits = 0;
  let numOfSpaces = -1;

  if (isPointingDown === true) {
    for (let i = 0; i <= numOfRows; i++) {
      numOfSpaces++;
      numOfUnits = numOfRows * 2 - 1;

      console.log(" ".repeat(numOfSpaces) + unitPattern.repeat(numOfUnits));

      numOfRows--;
    }
  }
}

console.log(pyramid("z", 5, true));

What does your function return exactly?

Also, you’ll need to refactor your for loop. You are incrementing one value and decrementing another, so I don’t think your loop is running as many times as you need it to.

Oh right, the number of rows would be decreasing so it wouldn’t finish, and then a function returns undefined without a return.. thank you so much for the pointers!
