you can use promise to resolve the above issue. 

billing = billingService(user_id).then(results => {
//Here in the results variable the output of billing service method will be stored if billing service method returns a promise.
recommendation = recommendation_service(user_id)})

Promise is the most efficient way to address asynchronous calls in javascript.

If you are specifically searcing for any library you can use ‘q’ library of node.js

You can try to use ES7’s async/await. It’ll be easier to write and your code will look a lot cleaner too.

Once you get it to work, your code will look something like:

const billing = await billingService(user_id)
const recommendation = await recommendation_service(user_id)

I’d recommend learning Promises too (afterall they’ve been successfully saving people from callback hell) to unmistify async/await (as your billingService and recommendation_service would eventually need to be async functions before they can be awaited)

Hope this helps!
