Are there any differences between these two pieces of code performance or bug wise?

I don't believe they do, but I found the second snippet in my codebase, so I wanted to be sure that I wasn't going to break something that I didn't try. Everything seems fine when I try it myself on my local server and test the functionality of what is being updated, but wanted to know if I was missing something, or some practice, by adding an empty array first

this.setState({ user: { ...(response || {}), ...data } });

this.setState({ user: { ...(response || {}), ...data } });

this.setState({ user: { ...response, ...data } });

this.setState({ user: { ...response, ...data } });
