Tell us what’s happening:

I cant seem to figure out why my code isn’t passing the test

Your code so far

function pyramid (pattern,int,boolean){

if (boolean === false){

let pyramidS = "";
let arrNum = [1,3,5,7,9];

for (let i = 0;i < int; i++){

pyramidS += " ".repeat(int-i-1);
pyramidS += pattern.repeat(arrNum[i]);
pyramidS += "\n";
}
return pyramidS
}

else if (boolean === true){

let pyramidS = "";
let arrNum = [9,7,5,3,1];

for (let i = 0;i < int; i++){

pyramidS += " ".repeat(i);
pyramidS += pattern.repeat(arrNum[i]);
pyramidS += "\n";
}
return pyramidS

}
}

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

There should be a new line \n at the beginning of the returned string.

Currently, pyramid("p", 5, true) returns:
ppppppppp\n ppppppp\n ppppp\n ppp\n p\n

but it should return:
\nppppppppp\n ppppppp\n ppppp\n ppp\n p\n

Here’s my new code. It still doesn’t pass the test.

function pyramid (pattern,int,boolean){

if(boolean === false){

let pyram = “”;
let count = 1;

for (let i = 0; i < int; i++) {

pyram += " ".repeat(int - i)
pyram += pattern.repeat(count);
pyram += “\n”
count += 2

}

return pyram

}

if(boolean === true){

let pyram = “”;
let count = int * 2 - 1;

for (let i = 1; i <= int; i++) {

pyram += " ".repeat(i);
pyram += pattern.repeat(count);
pyram += “\n”;
count -= 2;

     }

return pyram

 }

}

Assume int is 5 and boolean is false,

For the first row, the code creates 5 - 1 = 4 spaces, but it should be 3 spaces.
This causes every row to have one extra leading space.

Try this to compare the desired output with what your function currently returns:

console.log("\n   o\n  ooo\n ooooo\nooooooo\n")
console.log(pyramid("o", 4, false))

Assume int is 5 and boolean is true,

In this case, the first row will have 1 space, but it should have 0 spaces.
Again, this results in an extra leading space on every row.

See the difference:

console.log("\nppppppppp\n ppppppp\n  ppppp\n   ppp\n    p\n")
console.log(pyramid("p", 5, true))

One last thing: the pyram variable should start with a new line \n, but you initialized it as an empty string.

What does it return?

Here are some troubleshooting steps you can follow. Focus on one test at a time:

  1. Are there any errors or messages in the console?
  2. What is the requirement of the first failing test?
  3. Check the related User Story and ensure it’s followed precisely.
  4. What line of code implements this?
  5. What is the result of the code and does it match the requirement? (Write the value of a variable to the console at that point in the code if needed.)

If this does not help you solve the problem, please reply with answers to these questions.

I figured it out days ago thanks.. I just had to move one of the ‘newlines’ out of the loop.
