Is there a way to simultaneously view and send this JSON data to the server using console.log?

Question

Is there a way to simultaneously view and send this JSON data to the server using console.log?

I'm looking to inspect the JSON data being sent and received by the server, but I'm struggling to understand how promises work in this scenario.

When I use console.log() on the function body, I see Promise { pending }. Unfortunately, I can't log 'users' outside of the promise due to it being out of scope.

Is there a way for me to access the data inside the code block provided?

function getAll(req, res, next) {
    userService.getAll().then(users => res.json(users)).catch(err => 
next(err)); 
}

The expected output should be some JSON data displayed in the console.
