Refactoring to Use Arrow Functions

The video tutorial guides viewers through a challenge involving the use of arrow functions in JavaScript. It begins with setting up a new script and defining a method to filter incomplete tasks. The tutorial then demonstrates how to refactor code using ES6 syntax and arrow functions, integrating these concepts into a notes application. Finally, it emphasizes testing the refactored code to ensure functionality remains intact.

What is the purpose of creating a new script in the playground folder?

• To test new JavaScript libraries

• To work through the arrow function challenge

• To create a new notes application

• To learn about Node.js modules

What is the main goal of the challenge involving the tasks object?

• To create a method that filters incomplete tasks

• To refactor existing code

• To create a new JavaScript library

• To learn about Node.js

Which JavaScript feature is used to filter tasks in the challenge?

• Map function

• Filter function

• Reduce function

• For loop

Why are arrow functions not suitable for methods in JavaScript?

• They are too complex

• They cannot be used with arrays

• They are slower than regular functions

• They do not have their own 'this' context

What is the main task in the second challenge involving the notes application?

• To refactor all functions using ES6 syntax

• To create a new user interface

• To integrate a database

• To add new features to the application

What should be used for methods when refactoring functions in the notes application?

• ES5 syntax

• Anonymous functions

• ES6 method definition syntax

• Arrow functions

What is the benefit of using the ES6 shorthand syntax for methods?

• It is more concise and readable

• It makes the code longer

• It allows for dynamic typing

• It is compatible with older browsers

What should be done after refactoring the code to ensure it still works?

• Add more features

• Rewrite the entire codebase

• Test the application

• Remove all comments

Which function in the notes application cannot use the shorthand syntax due to multiple statements?

• removeNote

• addNote

• getNotes

• saveNotes

What is the purpose of using arrow functions in the refactoring process?

• To add new features

• To make the code more concise

• To improve performance

• To make the code more complex
