            Duration Object
          
          
            
              A duration is a way to express an amount of time that has passed. It can also be used to express a time-of-day, in other words, the amount of time that has passed since the start of the day.
            
          
        
      
        
          
            Date Formatting
          
          
            
              The term “date formatting” means taking a Date object and converting it into a string. The string can either be a standard string format like ISO8601 (ex: '2018-05-01') or it can be something more custom that you can display to users.
