Need function to construct iso duration string from given object about iso8601-duration HOT 5 CLOSED

export function secondsToISOString(seconds) {
  let Y = Math.floor(seconds / 60 / 60 / 24 / 365);
  let M = Math.floor(seconds / 60 / 60 / 24 / 30.42 % 12);
  let D = Math.floor(seconds / 60 / 60 / 24 % 30.42);
  let h = Math.floor(seconds / 60 / 60 % 24);
  let m = Math.floor(seconds / 60 % 60);
  let s = Math.floor(seconds % 60);

  if (!seconds) {
    return 'P0D';
  }

  return (
    (seconds < 0 ? '-' : '') +
    'P' +
    (Y ? Y + 'Y' : '') +
    (M ? M + 'M' : '') +
    (D ? D + 'D' : '') +
    (h || m || s ? 'T' : '') +
    (h ? h + 'H' : '') +
    (m ? m + 'M' : '') +
    (s ? s + 'S' : '')
  );
}

import test from 'tape';
import { secondsToISOString } from '../src/utils.js';

test('secondsToISOString', (t) => {
  t.equal(secondsToISOString(0), 'P0D');
  t.equal(secondsToISOString(120), 'PT2M');
  t.equal(secondsToISOString(3601), 'PT1H1S');
  t.equal(secondsToISOString(1), 'PT1S');
  t.equal(secondsToISOString(5410), 'PT1H30M10S');
  t.equal(secondsToISOString(37226652), 'P1Y2M4DT20H44M12S');
  t.equal(secondsToISOString(37313052), 'P1Y2M5DT20H44M12S');
  t.end();
});

new Temporal.Duration(0, 0, 0, 40); // => P40D
