Opinion, pyramid shape function

JavaScript
1

Hey folks,
I’m doing FCC top 10 js algorithm exercices YT video
I’d love to have feedback on 2 possible solutions for the pyramid shape function

Given an integer, the function logs to console a pyramid shape, example

//   pyramid(2)
//       ' # ' 
//       '###'

Here’s my solution (basically I “measure” the distance from the center to determine which character must be added to str)

function pyramid(n) {
    for (let i = 1; i<= n; i++) {
        let str = ''
        for (let j = 1; j <= 2*n-1; j++) {
            if (Math.abs(j-n) < i) {
                str += '#'
            }else{
                str += ' '
            }
        }
        console.log(str)
    }
}

Whereas the suggested solution does something slightly different, see below.
I’m trying to get good coding habits, and I was wondering if there was one reason to prefer one solution over the other, or if they are equivalent.
Thank you!!!

function pyramid(n) {
  const mid = Math.floor((2*n-1)/2)
  for(let row=0; row<n; row++){
    let line = ''
    for(let col=0; col<2*n-1; col++){
      if( col >= mid - row && col<= mid + row ){
        line += '#'
      }else{
        line += ' '
      }
    }
    console.log(line)
  }
}

if you want an even different way, you can do the Pyramid Generator project in the curriculum: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures-v8/#learn-introductory-javascript-by-building-a-pyramid-generator

there isn’t necessarily a best way to do this

Thank you for pointing me there, I planned to go through the curriculum as soon as I finished the YT exercices, this looks great!
