Tips, Tricks, and Techniques for Node.js Development 3.4: Generators and Yield

This video tutorial explains how to use generator functions with the yield keyword to handle synchronous code. It covers the creation and implementation of generator functions, refactoring existing code, and managing errors during execution. The tutorial concludes with a summary and a preview of the next topic, async/await.

What is the primary purpose of using the yield keyword in a generator function?

• To define a new function

• To pause and resume a function

• To declare a variable

• To end a function

Which of the following is NOT a characteristic of a generator function?

• It can pause execution

• It is defined using an arrow function

• It can return multiple values over time

• It uses the yield keyword

Why should arrow functions be avoided in generator functions?

• They are slower than regular functions

• They require more memory

• They do not support the yield keyword

• They are not compatible with async/await

What is the role of the run function in executing generator functions?

• To handle errors in the generator

• To initialize the generator

• To extract all data from the generator

• To convert the generator to a synchronous function

What is the next topic to be covered after learning about generator functions and yield?

• Promises

• Async/Await

• Error handling in JavaScript

• Event Loop
