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.
