Tell us what’s happening:

i think i get the desired result, but where did i got wrong?

Your code so far

function pyramid(str,integer,boolean){
  let result = [];
  if (boolean === true){
    for (let i=integer; i>=0; i--){
      result.push(" ".repeat(integer - i) + str.repeat(1.8*i))
    } 
  }
  if (boolean === false){
    for (let i=0; i<=integer; i++){
      result.push(" ".repeat(integer - i) + str.repeat(1.8*i))
    }
  } 
  return result.join("\n");
}

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

one of the failed messages you have says:
pyramid("o", 4, false) should return "\n o\n ooo\n ooooo\nooooooo\n".

See how it starts with a newline?
In your case, do you think what you are making starts with a newline?
(also note the ending newline)

This is as per this instruction that was given

  1. The pyramid should start and end with a newline character.

Edit: also you should double check the spaces you are using. I think you are outputting an extra line of spaces

function pyramid(str,integer,boolean){
  let result = [];
  if (boolean === false){
    for (let i=0; i<integer; i++){
      result.push(" ".repeat(integer - i -1) + str.repeat(i * 2 + 1))
    }
  }
  if (boolean === true){
    for (let i=integer; i>0; i--){
      result.push(" ".repeat(integer - i) + str.repeat(i * 2 - 1))
    } 
  }
  return "\n" + result.join("\n");
}

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

still not passing

try changing your logging to

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

so you can confront the strings in the same format they are shown in the hints
