Right-hand side of 'instanceof' is not an object Error

This code doesn’t work idk why
$(eval if(!$(query)){Please ask a Question ( !8ball <Question> )}else{r=[“It is certain”,”It is decidedly so”,”Without a doubt”,”Yes definitely”,”You may rely on it”,”As I see it, yes”,”Most likely”,”Yes”,”Signs point to yes”,”Reply hazy, try again”,”Ask again later”,”Better not tell you now”,”Cannot predict now”,”Don’t count on it”,”My reply is no”,”My sources say no”,”Very doubtful”];(r[ Math.floor(Math.random() * r.length) ])+ @$(user)})
Please help. I feel like maybe twitch has changed stuff recently because most commands don’t work now all of a sudden.
