Steps

Instructions:

• Write a function that accepts a positive number N. The function should console log a step shape with N levels using the # character. Make sure the step has spaces on the right hand side!

Examples:

steps(2)
  '# '
  '##'
steps(3)
  '#  '
  '## '
  '###'
steps(4)
  '#   '
  '##  '
  '### '
  '####'

Code:

// First(🥑)
function steps(n) {
  for (let row = 0; row < n; row++) {
    let stair = '';
    for (let column = 0; column < n; column++) {
      if (column <= row) {
        stair += '#';
      } else {
        stair += ' ';
      }
    }
    console.log(stair);
  }
}
// Second (🥦)
function steps(n, row = 0, stair = '') {
  if (n === row) {
    return;
  }
  if (n === stair.length) {
    console.log(stair);
    return steps(n, row + 1);
  }
  if (stair.length <= row) {
    stair += '#';
  } else {
    stair += ' ';
  }
  steps(n, row, stair);
}
