title: compare timestamps in javascript
body: <p>I have a date saved in a string with this format: <code>2017-09-28T22:59:02.448804522Z</code> this value is provided by a backend service.</p>
  
  <p>Now, in javascript how can I compare if that timestamp is greater than the current timestamp? I mean, I need to know if that time happened or not yet taking in count the hours and minutes, not only the date.</p>
