How to return a value from an object function when called inside a JavaScript function

Question

I would like to create a HTTP request inside a function using the request-json npm package.

Here is the code for the same:

request = require('request-json')
client = request.createClient('http://localhost:5000')

function getData(){
    
    client.get('/currentdata', function(err, res, body){
        return console.log(body)
    })
    
}

getData()

This works fine on the console, but when I try return body instead of return console.log(body), and change my function call statement as var x = getData(); console.log(x);, it gives me undefined as output.

I would like to know how to return a value from inside the client.get function to the main area, going through the getData() function.
