How do I use Javascript with ? [duplicate]

I have a block of Javascript to pull a random gif that looks like this:

const gifs = ["1.gif", "2.gif", "3.gif"];

const random = Math.floor(Math.random() * gifs.length);
console.log(random, gifs[random]);

I want to place a gif inside an <img> tag, like <img src="1.gif"> by using the random const to pull a random gif each time the page loads.

I added document.getElementById("giffetch").innerHTML = gifs; and <img id="giffetch">, but it didn’t work. I sense I’m close but missing a crucial element.
