play pause html5 video javascript

$('#play-pause-button').click(function () {
   var mediaVideo = $("#media-video").get(0);
   if (mediaVideo.paused) {
       mediaVideo.play();
   } else {
       mediaVideo.pause();
  }
});

I have done this in jQuery, which is simple and fast. To try it, you just need to use the ID of the video tag and your play/pause button.

EDIT:
In vanilla JavaScript:
a video is not a function, but part of DOM hence use

 video.play(); 

Instead of

video().play() **wrong**
