I received a question about this snippet of code:

function def(first="oldValue" , second=function(){
         return first;
}){
        var first="updatedValue";
        console.log('inside',first);
        console.log('function',second());
}

ECMAScript

Async/Await

We should not forget await

Quoting [We should not forget the await (Exploring ECMASCript 2016-2017; 5.3.1 Don’t forget await][public-book-exploring2016-17-async-do-not-forget-await])

[out value] is set to a Promise, which is usually not what you want in async functions. await can even make sense if an async function doesn’t return anything.
