When working with asynchronous operations, you can use async/await with a forEach loop to handle asynchronous tasks in a more readable and sequential manner. However, it’s important to note that forEach itself does not directly support async/await because it does not wait for promises to resolve. Instead, we need to use other options, such as for…of or for loops, in conjunction with async/await.
Here’s an example of how you can use async/await with a for…of loop to iterate over an array and handle asynchronous tasks:
const myArray = [1, 2, 3, 4, 5]; const performAsyncTask = async (item) => { // Simulating an asynchronous task return new Promise((resolve) => { setTimeout(() => { console.log(`Processed item: ${item}`); resolve(); }, Math.random() * 1000); }); }; const processArray = async (array) => { for (const item of array) { await performAsyncTask(item); } console.log('All items processed'); }; processArray(myArray) .then(() => { console.log('Processing completed'); }) .catch((error) => { console.error('An error occurred:', error); });
In this example, performAsyncTask is an asynchronous function that simulates some time-consuming operations. The processArray function iterates over the myArray using a for…of loop, and for each item, it awaits the completion of performAsyncTask. This ensures that each asynchronous task is executed sequentially.
