Moyes says the performance offered a glimpse of the potential of his team. Beto, Iliman Ndiaye and Kiernan Dewsbury-Hall struck the goals for the visitors.
The Scot said afterwards: "I liked bits of the performance. I still would have liked it to have been much better. We conceded two goals which I don't think were like us, the type of goals they were. They were a bit easy and not the things we work on and we're quite good at.
"So I was disappointed with that, a bit disappointed when we were 3-1 up that we didn't go and get the fourth goal, which we had three or four opportunities. But the answer to your question is, you know, we've come away from home with a really good win.
"If we can entertain and be really good, great. If we can't, then I just want to win. That's what I want to do.
"Kiernan played very well today. So did many of them, but he'd done a really good job. So, you know, Jack's beginning to get some assists. He's looking a good player for us and really pleased to have him at the moment.
"The biggest compliment I can say about Jack is that he's even better than I thought he was."
Barry and Beto plan
Moyes also revealed a rotation plan for centre-forwards Beto and Thierno Barry.
"I'm going to change Beto and Barry around, I want to try to keep them fresh," he said. "I wanted Barry to get some game time which he did do and he did a great job at Brighton, assisting the goals with his link-up play. But I just felt maybe Beto might have been the right one to come here and know a wee bit of their ground and what it might be like.
"But I need the two of them, we'll be firing, I need the two of them, we'll be scoring goals and we might chop and change them as we see at different times.
"But Beto's just got two goals now, got one in midweek, got one today. And that's what you need to do as a striker. You just need to keep getting the goals and he starts to get the numbers a lot bigger."
