Javascript LoadMore Feature

1. Setup and Global State First, you select your HTML elements and define the variables that track your progress: DOM Elements: todoList and loadMoreBtn . State Variables: limit (set to 50), skip (starts at 0), and totalTodos (starts at 0) . 2. The Asynchronous Fetch Logic The fetchTodos function is an async function that manages the API call and the button's state : UI Feedback: It immediately disables the button and sets the text to 'Loading...' . Error Handling: It uses a try...catch block to log errors and update the button text to 'Error' if something goes wrong . 3. The Rendering Function The renderTodos function takes the array of todos and updates the page: Looping: It uses forEach to iterate through each todo . Creation: It creates a new li element for every item . Formatting: It sets the textContent using a template that includes the id, a completion icon (✅ or ❌), and the todo text . Appending: Finally, it attaches each list item to the todoList . 4. Initialization and Events The last part connects everything to the user interface: Event Listener: It adds a 'click' listener to the loadMoreBtn to trigger fetchTodos . Initial Load: It calls fetchTodos() once at the start so the list isn't empty when the page first opens .
