Using async/await with a forEach Loop

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.
