The Modern JavaScript Bootcamp (2019) - Splitting up Our Application Code

The video tutorial discusses the process of refactoring, which involves restructuring code without altering its external behavior. It emphasizes the importance of organizing code into separate JavaScript files and using functions to enhance code readability and maintainability. The tutorial also covers the concept of the global namespace in JavaScript and demonstrates how to refactor code by creating reusable functions. Testing the refactored code and ensuring it functions as expected is highlighted. The video concludes with a summary of the refactoring process and introduces the next steps for further learning.

What is the primary goal of refactoring code?

• To add new features quickly

• To reduce the number of lines of code

• To improve code structure without changing its behavior

• To make the code run faster

Why is it beneficial to abstract features into function calls?

• It reduces the file size

• It eliminates the need for comments

• It makes the code run faster

• It allows for easier code maintenance and readability

What is the benefit of having a separate JavaScript file for functions?

• It makes the code run slower

• It makes the code harder to debug

• It allows for better organization and reuse of code

• It increases the file size

What happens if JavaScript files are not loaded in the correct order?

• The browser will crash

• The scripts will not execute at all

• Variables and functions may not be available when needed

• The HTML will not render

What is a key consideration when working with multiple JavaScript files?

• The color scheme of the code editor

• The number of functions in each file

• The size of each file

• The order of script tags in HTML

What is the purpose of creating a function to fetch data from local storage?

• To ensure data is always fetched in the same way

• To make the code more complex

• To increase the speed of data retrieval

• To reduce the number of files

How can refactoring improve the process of adding new features?

• By increasing the number of files

• By making the code easier to understand and modify

• By reducing the number of lines of code

• By making the code more complex

How does breaking code into smaller functions help in code maintenance?

• It allows for easier updates and feature additions

• It increases the number of bugs

• It makes the code run slower

• It makes the code harder to understand

What is a potential downside of excessive refactoring?

• It can lead to unnecessary complexity

• It can make the code run faster

• It can reduce the number of features

• It can make the code too simple

Why might someone choose to abstract away the use of local storage?

• To make the code dependent on local storage

• To reduce the number of function calls

• To allow for easy changes to the storage mechanism

• To increase the complexity of the code
