How would I convert this promise to an async / await function?
Here's my Promise:
How would I convert that to an "async / await" dynamic?
$(document).ready(function() {
const fetchData = () => {
const promise = new Promise((resolve, reject) => {
setTimeout(() => {
resolve("Loose Cannon Fitness");
}, 100);
});
return promise;
};
setTimeout(() => {
console.log("Smith and Gone");
fetchData()
.then(text => {
console.log(text);
});
}, 200);
});

async / await is declared at the function level - you cannot do it at the global level. [for interest]
The syntax is
In your case we make the arrow function async
The syntax is
function async someFunction() {
var promiseResult = await somePromise;
// use promiseReulst here
}
In your case we make the arrow function async
setTimeout( async () => {
console.log("Smith and Gone");
var text = await fetchData();
console.log(text);
}, 200);

As always, thank you for a thorough explanation!
What you've got works, but I've got one more related question and let me qualify it by saying that at this point, it's not about practical application as much as it's for my own edification.
Could I write "fetchData" as an anonymous function? Not that I would necessarily do that in a practical setting, but I was curious.
