How to use format() on a moment.js duration?

Question

Is there any way I can use the moment.js format method on duration objects? I can\'t find it anywhere in the docs and it doesn\'t seen to be an attribute on du

Answer 1

This can be used to get the first two characters as hours and last two as minutes. Same logic may be applied to seconds.

/**
     * PT1H30M -> 0130
     * @param {ISO String} isoString
     * @return {string} absolute 4 digit number HH:mm
     */

    const parseIsoToAbsolute = (isoString) => {
    
      const durations = moment.duration(isoString).as('seconds');
      const momentInSeconds = moment.duration(durations, 'seconds');
    
      let hours = momentInSeconds.asHours().toString().length < 2
        ? momentInSeconds.asHours().toString().padStart(2, '0') : momentInSeconds.asHours().toString();
        
      if (!Number.isInteger(Number(hours))) hours = '0'+ Math.floor(hours);
    
      const minutes = momentInSeconds.minutes().toString().length < 2
        ? momentInSeconds.minutes().toString().padEnd(2, '0') : momentInSeconds.minutes().toString();
    
      const absolute = hours + minutes;
      return absolute;
    };
    
    console.log(parseIsoToAbsolute('PT1H30M'));
