if statement suggestion

I have a javascript i want to compress a little

The basic idea is it looks for files from a json file If the file is MP4,mkv,avi, < any video format. It appends the url in a tag

if its an image it does the same With an tag.

here is my code.

//example
var link = "video.mp4";

var videoorimg = link.split(".").pop(1);
        if(videoorimg === "mp4"){
          $("body").append('<video src="'+ link +'">');
        }
        if(videoorimg === "jpg"){
          $("body").append('<img src="'+ link +'">');
        }
        

this is fine. How ever im running into issues where there is multiple file types for images and video.

My idea was an array like this.

//example
function imgarry(){
jpg,
png,
jpeg,
bmp,
tiff,
}

function videoarry(){
mkv,
mp4,
mov,
avi,
m4v,
}


var link = "video.mp4";

var videoorimg = link.split(".").pop(1);
        if(videoorimg === videoarry() ){
          $("body").append('<video src="'+ link +'">');
        }
        if(videoorimg === imgarry() ){
          $("body").append('<img src="'+ link +'">');
        }

how ever i know this is incorrect, Is there a way i can achieve this though?
