The Modern JavaScript Bootcamp (2019) - Refactor Challenge

The video tutorial focuses on refactoring a Todo application by organizing JavaScript functions into separate files. It covers defining and linking functions, implementing getSavedTodos and saveTodos for local storage, and creating renderTodos and generateTodoDom for DOM manipulation. The tutorial emphasizes testing each function individually to ensure functionality remains intact. The final section introduces generateSummaryDom and demonstrates testing the refactored application.

What is the primary focus of the Todo application tutorial?

• Creating a new HTML file

• Defining and using functions across files

• Learning CSS styling

• Understanding server-side scripting

Which function is responsible for fetching data from local storage?

• saveTodos

• generateSummaryDom

• renderTodos

• getSavedTodos

What is the purpose of the saveTodos function?

• To fetch data from an API

• To generate the DOM structure

• To save data to local storage

• To render the Todo list

Why is it important to load the JavaScript file before using its functions?

• To reduce file size

• To enhance security

• To improve page load speed

• To ensure the functions are defined before use

What is the benefit of refactoring code one function at a time?

• It increases code complexity

• It makes debugging easier

• It speeds up the application

• It reduces the number of files

Which function is used to generate the DOM for each Todo item?

• renderTodos

• generateTodoDom

• getSavedTodos

• generateSummaryDom

What is the role of the generateSummaryDom function?

• To save Todos to local storage

• To fetch Todos from local storage

• To create a summary of incomplete Todos

• To render the entire Todo list

How does refactoring benefit the expansion of the application?

• It makes adding new features easier

• It increases the number of lines of code

• It reduces the need for comments

• It complicates the code structure

What is the next topic to be covered after refactoring?

• Styling with CSS

• Debugging techniques

• Server-side scripting

• Database management

What is the main advantage of organizing code into functions?

• It simplifies the code structure

• It increases the complexity

• It makes the code run faster

• It reduces the number of files
