- The code fetches all todos from a mock API using the `getTodos` function.
- It adds a new todo item to the API using the `addTodo` function when the user clicks the add button.
- It updates the status of a todo item in the API using the `updateTodo` function when the user checks or unchecks the checkbox associated with the todo item.
- It deletes a todo item from the API using the `deleteTodo` function when the user clicks the delete button associated with the todo item.
- Upon page load (`DOMContentLoaded` event), it fills the todo list with the fetched todos using the `fillTodoList` function.
- The `createLI` function creates a new list item (li element) for each todo item, including a checkbox for the todo status, text for the todo description, and a delete button.
- This version clears the existing list items (myUL.innerHTML = '') and then rebuilds the entire todo list by calling fillTodoList().
- Advantage: Ensures that the todo list is completely updated and reflects the current state of todos from the API.
- Consideration: It might be less efficient to rebuild the entire list if only one todo is added. However, it guarantees consistency with the server data.
