Is there a way to trigger a callback function in the scan function after the for await loop completes?
let personObj = {};
let personArray = [];
async function scan() {
for await (const person of mapper.scan({valueConstructor: Person})) {
decrypt(person.name, function () {
personArray.push(personObj);
});
}
}
For instance, I am thinking of executing console.log(personArray) once the loop finishes.
To utilize the callback function in an async function, you should consider promisifying it:
function transformAsync(data) {
return new Promise(resolve => {
transform(data, resolve);
});
}
async function process() {
let itemArray = [];
for await (const item of dataProcessor.process({dataType: Item})) {
let transformedItem = await transformAsync(item.info);
itemArray.push(transformedItem);
}
console.log(itemArray);
}
