Understanding async/await on NodeJS

Question

I think my understanding of it might be affected by my experience with .NET\'s async/await, so I\'d like some code example:

async await are just syntactic sugar for promises.

you use them like you use promises when you want your code to run on complete of a function.

async function asyncOperation(callback) {
    const response = await asyncStep1();
    return await asyncStep2(response);
}

is the exact thing if you used promises land syntax:

function asyncOperation() {
  return asyncStep1(...)
    .then(asyncStep2(...));
}

The new async/await syntax allows you to still use Promises, but it eliminates the need for providing a callback to the chained then() methods.

The callback is instead returned directly from the asynchronous function, just as if it were a synchronous blocking function.

let value = await myPromisifiedFunction(); 

When you are planning to use await in your function you should mark your function with async keyword (like in c#)

You don't have to create your getUsers as anonymous function.
