    padStart also can be used to solve this, for adding padding on string.

    developer.mozilla.org/en-US/docs/W...

    function staircase(n) {
  for (let i = 0; i < n; i++) {
    const line = Array(i + 1)
      .fill("#")
      .join("")
      .padStart(n);
    console.log(line);
  }
}
    Enter fullscreen mode Exit fullscreen mode

    function staircase(n) {
    // Write your code here
    let string = "";
    for (let j = n; j > 0; j--) {
    for (let i = 1; i <= n; i++) {
    if (i < j) {
    string += " ";
    continue;
    }
    string += "#";
    }
    if (j === 1) {
    continue;
    }

    string += "\n";
    Enter fullscreen mode Exit fullscreen mode

    }
    console.log(string);

    }

    what's the issue with this one!! However, as soon as I run the code on the console it's given me the same output as the one on HackerRank but whenever I sumbit the code through hackerRnak' website ,the compiler message is telling me back the code I wrore was wrong!!
    function drawTriangle(n) {
    let j = "#";
    let i = 1;
    let myTriangle = "";
    while (i <= n) {
    myTriangle += "\n" + j;
    j += "#";
    i++;
    }
    console.log(myTriangle);
    }

    this for java
    for(int i = 1; i <= n ; i++){
    int freesSpace = n - i ;
    for(int a = 1; a<=freesSpace;a++){
    System.out.print(" ");
    } for(int b = 1; b<=i;b++){
    System.out.print("#");
    }
    System.out.print("\n");
    }
    }

    and all the HackerRan Solution it is in my GitHub
