How can I calculate the time between 2 Dates in typescript

Question

This works in Javascript

new Date()-new Date(\"2013-02-20T12:01:04.753Z\")

But in typescript I can\'t rest two new Dates

Date(\         


        

Answer 1

This is how it should be done in typescript:

(new Date()).valueOf() - (new Date("2013-02-20T12:01:04.753Z")).valueOf()

Better readability:

      var eventStartTime = new Date(event.startTime);
      var eventEndTime = new Date(event.endTime);
      var duration = eventEndTime.valueOf() - eventStartTime.valueOf();
