Tell us what’s happening:

i think i did well yet , but i don’t pass . what should i do more than that ? could anyone give hint ?

Your code so far


function pyramid(str, num, bool) {
  for(let i = 0; i < num; i++) {
    let row = ''

    if(!bool) {
      for(let j = 0; j < num - i - 1; j++) {

      row += ' '
      }
    } else {
        for(let j = num; j > num - i - 1; j--) {

      row += ' '
      }
    }
    if(!bool) {
      for(let k = 0; k < 2 * i + 1; k++) {
       row += str 
   
      }
    } else {
      for(let k = 2 * num - 2; k > 2 * i - 1; k--) {
      row += str 
      }
    }
      console.log(row)
  }
}
pyramid('o', 5, false)

what is your function returning?

3

if i return i don’t get the output that i want i just log it on the console

4

But what do the user stories say?

like, User story 5 starts with “The pyramid function should return”, the tests also use “should return”

are you sure your approach is correct?

hi @SamehCode01

pyramid("o", 4, false) should return "\n o\n ooo\n ooooo\nooooooo\n".

Do you add a newline character to the beginning of each line?

To test you can print the raw output with:
console.log(JSON.stringify(row));

6

instead of this, you should log the function call, console.log(JSON.stringify(pyramid("o", 4, false)));

Indeed we need to aggregate the rows to return.

um no iam not sure :stuck_out_tongue: cuz of your words i feel i walk in the wrong way . did u observed my code and how i managed somethings like true false with ! in condition , that was genius from me i feel good with this what u c boss ?

oic i will try to rebuild it again , thank you

you need a good job with that, now you need to figure out how to create a string to return instead of using console.log for each row

Just to add to what’s been said already.

To see the returned output as a pyramid:

console.log(pyramid('o', 5, false))

To see the returned output as a RAW string to compare with the tests:

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

Both are useful

i need to storm my brain first for a while

13

to be honest i searched for this problem on google and i observed solution but i did not copy the code i manipulate it myself , in addition to conditions i added and manipulate reversing pyramid depending on true/false all that i did myself

14

now i try to build it from scratch again , but i still meet a problem somehow should i observe it again for review ?

15

no, keep trying on your own, use the output to know what you need to change

if you know what you need to change but don’t know how, you can ask for help

16

i will try to discover it my self

17

look how i test it on the console

console.log(hasPassingGrade(getGrade(getAverage([38, 99, 87, 100, 100, 100, 100, 100, 100, 100]))))

oO seems i mixed the problem with another challenge

18

that does not look like a function call you would use in this lab

19

yea i missed up , i was just working with gradebook app . wohoooo i just passed it right now , you know this feeling man , this feeeeeeeeeeling after success

20

no man i can’t do that :smiley: . i feel my brain stopped working like computer bugs . i think i will bookmark those challenges and i will practice it more in the future
