Try below method.

var a;
var n = 5;
for (var i = 1; i <= n; i++) {
  for (var j = 1; j <= i; j++) {
    document.write(j + " ");
  }
  document.write("<br />");
}

Try below code:

function createPyramid(rows) {
  for (var i = 0; i < rows; i++) {
    var output = '';
    for (var j = 0; j < rows - i; j++) output += ' ';
    for (var k = 0; k <= i; k++) output += (i + 1) + ' ';
    console.log(output);
  }
}

createPyramid(4);
