Promisifying fs

Each exercise file contains fully working code. You need to refactor each one twice using promisified fs functions:

• once as standard promises
• once using async/await

Getting Started

• Clone the repo
• Get coding! (there are no dependencies)

Learning Objectives

• Using util.promisify
• Using promisifyed fs
• Refactoring from callbacks to promises
• Refactoring from callbacks to async/await
• Refactoring synchronous to asynchronous
