Nested Loops
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); } } steps(4)
Recursion
function steps2(n, row = 0, stair = "") { if (n === row) { return; } if (n === stair.length) { console.log(stair); steps2(n, row + 1); return; } if (stair.length <= row) { stair += "#"; } else { stair += " "; } steps2(n, row, stair); } steps2(4)
