when/how to use async & await site:stackoverflow.com code example
Example: async await javascript stack overflow
function makePromise(x) {
return new Promise(resolve => {
setTimeout(() => {
resolve(x);
}, 1000);
});
}
async function asyncFunc() {
var x = await makePromise(1); // the function is paused here until the promise is fulfilled
console.log(x); // logs 1
return x;
}
const returnedProm = asyncFunc(); // the async func returns a promise
returnedProm.then((x) => console.log(x));
// This promise is fulfilled with the return value from the async func, so this logs 1
