Date difference in hours - Angular 2

Question

How can I get difference in hours between two dates in angular2? I don\'t want to use external libs like moment.js.

Having, for example: incidentTi

Answer 1

This should do the job:

const date1 = params.data.incidentTime;
const date2 = params.data.creationTime;

const diffInMs = Date.parse(date2) - Date.parse(date1);
const diffInHours = diffInMs / 1000 / 60 / 60;

console.log(diffInHours);

Use Math.floor to round the result down, or Math.ceil to round it up
