Build a Pyramid Generator - Build a Pyramid Generator

Ensure the output starts with a newline.

You aren’t added the result of repeating to the variable in both loops.

22

Now I am getting the desired result but test not passing.

23

show your updated code

24

Here’s the code → 

function pyramid(character, rows, isInverted) {
  let level = "";
  if(isInverted === false) {
    for(let i = 1; i <= rows; i++) {
      level += " ".repeat(rows-i) + character.repeat(2 * i -1) + "\n";
    }
  }
  else {
    for(let i = rows; i >= 1; i--) {
      level += " ".repeat(rows-i) + character.repeat(2 * i -1) + "\n";
  }
} return level;
}

console.log(pyramid("o", 4, false));
console.log(pyramid("p", 5, true));

Hello Ilenia, happy to see you again :slight_smile: I shared updated code above

26

Right now it is not easy to compare the expected result with the output, so we can use the JSON.stringify function

console.log(JSON.stringify(pyramid("o", 4, false)));
console.log(JSON.stringify(pyramid("p", 5, true)));

This outputs

"   o\n  ooo\n ooooo\nooooooo\n"
"ppppppppp\n ppppppp\n  ppppp\n   ppp\n    p\n"

and you can compare it with the two desired outputs:

"\n   o\n  ooo\n ooooo\nooooooo\n"
"\nppppppppp\n ppppppp\n  ppppp\n   ppp\n    p\n"

you are almost there, you are missing a thing at the beginning of the strings

27

Yes there should be one extra \n in beginning of both outputs

29

I don’t understand how to fix that single \n at beginning, due to loop it will get repeated and I only want it once. But why do I even need it ?

30

I fixed it, lesson passed but why do I even need it ? Please explain.

return "\n" + level;
31

it’s part of the requirements so it must be there

32

okay got it, thank you.

Thanks a lot @hasanzaib1389 @ILM and @Teller :slight_smile:
