How to pull out a variable?

Question

Node.js

What are the options to move the data variable to the s variable?

var s;
                s = aut().then(function(data){
                    return data
                });
console.log(s);

Answer 1

If ES6 is supported, use async/await: If not, then you are correct:

var s;
aut().then(data => {
  s = data;
});

But right after that, you can't console.log because the function is asynchronous. The variable s will be set when the aut() function is executed. It would be better to do:

var s;
aut().then(data => {
  s = data;
  console.log(s);
});
