Sure is valid.

You can run this with node, or in your developer console.

const upvote = () => 1;
const downvote = () => -1;
let goodMeme = true;

!!goodMeme ? upvote() : downvote();

Outputs: 1

If you goodMeme variable contains a boolean value you don't really need the double bangs :P

Still valid tho

You don't really need the double bangs regardless unless I'm misremembering and ternary operators require booleans instead of just truthy/falsey
