Write a Node.js function to handle asynchronous operations using async/await.

Question

Aryan Kumar · Answer

Sure, here is an example of a Node.js function to handle asynchronous operations using async/await:

JavaScript

const fs = require('fs');

async function handleAsyncOperations() {
  const data1 = await fs.readFile('data1.txt');
  const data2 = await fs.readFile('data2.txt');

  console.log(data1);
  console.log(data2);
}

handleAsyncOperations();

This function first imports the fs module, which provides access to the file system. The function then defines an async function called handleAsyncOperations(). The handleAsyncOperations() function uses the await keyword to wait for the results of the fs.readFile() asynchronous operations.

The fs.readFile() method returns a promise, which is a special object that represents the eventual result of an asynchronous operation. The await keyword can be used to wait for the promise to resolve, and then the result of the promise is assigned to the variable.

In this example, the handleAsyncOperations() function first reads the file data1.txt and then reads the file data2.txt. The results of the two read operations are then logged to the console.

To run this function, you can save it as a file called handleAsyncOperations.js and then run it from the command line:

node handleAsyncOperations.js

This will run the handleAsyncOperations() function and log the contents of the two files to the console.
