Tips, Tricks, and Techniques for Node.js Development 3.5: Async Await Now

The video tutorial introduces async/await in JavaScript, explaining how these keywords can make asynchronous code look synchronous. It covers the transition from generator functions to async/await, detailing the necessary code changes. The tutorial also explains how to transform functions to return promises and demonstrates implementing async/await in file reading operations. The session concludes with a summary and a preview of the next topic, unit testing.

What is the primary benefit of using async/await in JavaScript?

• It makes asynchronous code run faster.

• It allows asynchronous code to be written in a synchronous style.

• It eliminates the need for promises.

• It automatically handles errors in asynchronous code.

When transitioning from generator functions to async/await, which keyword is used to replace 'yield'?

• async

• then

• promise

• await

What must be done to a function to use it with async/await?

• Make it a synchronous function.

• Convert it into a callback function.

• Transform it into a promise.

• Use the 'yield' keyword.
