Promisifying Callback-based Asynchronous Functions

Introduction

In this project, you will learn how to promisify a callback-based asynchronous function in JavaScript. Specifically, you will convert the callback-based readFile function from the fs module in Node.js into a Promise-based version.

🎯 Tasks

In this project, you will learn:

• How to identify the conditions for promisifying a function
• How to implement a promisefy function to wrap a callback-based function and return a Promise
• How to use the Promise-based version of the readFile function to read a file asynchronously

🏆 Achievements

After completing this project, you will be able to:

• Understand the benefits of using Promises over callback-based asynchronous programming
• Implement a generic promisefy function to convert callback-based functions into Promise-based ones
• Utilize Promise-based asynchronous functions in your own projects to improve code readability and error handling
