Ans works:

It only works if I make pyramid function return and check it in the main function part. Why is that?

Your code so far

const pyramid = function (str, Nrow, bool){
  let whole = "";
  if(bool){
    for(let i = Nrow; i > 0; i= i - 1){
      whole = whole.concat("\n");
      let spaces = "";
      let line = "";
      for(let k = 0; k< Nrow-i; k= k + 1){
        spaces = spaces.concat(" ");
      }
      for(let j = 0; j< 2*i-1; j= j + 1){
        line = line.concat(str);
      }
        // spaces = spaces.slice(0,Nrow-i-1);
      // console.log(spaces, line);
      line = spaces.concat(line);
      whole = whole.concat(line);
    } 
    whole = whole.concat("\n");
    console.log(whole);
  }
  else{
    // console.log("\n");
    for(let i = 0; i< Nrow; i= i + 1){
      whole = whole.concat("\n");
      let spaces = "", line = "";
      for(let j = 0; j< Nrow-1-i; j= j + 1){
        spaces = spaces.concat(" ");
      }
      for(let j = 0; j< 2*(i+1)-1; j= j + 1){
        line = line.concat(str);
      }
      // spaces = spaces.slice(0,Nrow-i-1);
      // if (i < 2){
        // spaces = " ";
        line = spaces.concat(line);
      // }
      // console.log(line);
      whole = whole.concat(line);
    } 
    whole = whole.concat("\n");
    console.log(whole);
  }
  
  return whole;
}
let ans = "";
let check = "";
check = pyramid("o", 4, false);
console.log("case check:", check==ans);

check = pyramid("p", 5, true);
console.log("case check:", check==ans);

Welcome to the forum @urbaner3,

Your solution works from my end.

I’m not sure I understand what you are asking about. Your function should return a string, which it does. And you do not need to check what it returns to pass the tests.

Happy coding
