Summary of "How to create a Todo List App Using HTML, CSS & JavaScript | JavaScript Project tutorial"

The video tutorial guides viewers through building a fully functional Todo List application using HTML, CSS, and JavaScript, emphasizing practical project development with enhanced features.

Key Technological Concepts & Features:

CRUD Operations on DOM Elements: The app supports Creating, Reading, Updating, and Deleting tasks dynamically in the UI.
Local Storage Integration: Tasks are saved in the browser’s Local Storage to persist data across page reloads and browser sessions.
Progress Bar: A visually animated progress bar updates in real-time reflecting the percentage of completed tasks.
Task Counters: Numerical display shows the count of completed versus total tasks (e.g., 2x3).
Task Management Features: Users can add tasks, mark them as completed (checkbox toggle), edit existing tasks, and delete tasks.
Animations: Confetti animation triggers when all tasks are completed, adding a fun, interactive element to the app.
Responsive UI Design: Utilizes Flexbox for layout, with styled containers for stats, input form, and task list.
Form Handling: Prevents default form submission behavior to allow JavaScript handling of task addition.
Event Listeners: Used for button clicks, checkbox toggles, and DOM content loading to manage app state and UI updates.
Code Organization: Uses arrow functions, modular functions for adding, updating, toggling, editing, and deleting tasks.
CSS Styling: Includes global resets, custom colors, border-radius, padding, margins, flex layouts, and styling for buttons, inputs, and task items.

Development Workflow Covered:

Project Setup: Creating project folder and files (index.HTML, styles.CSS, app.js).
HTML Structure: Building container divs for stats, input form, and task list.
CSS Styling: Defining colors, flexbox layouts, progress bar styles, buttons, inputs, and task list appearance.
JavaScript Logic:
- Managing task array as the data model.
- Adding tasks from input with validation (ignoring empty or whitespace-only entries).
- Rendering tasks dynamically in the DOM with checkboxes, task text, and edit/delete icons.
- Implementing toggle complete, edit, and delete functionalities.
- Updating progress bar and task counters based on task completion.
- Persisting tasks to Local Storage and retrieving them on page load.
- Adding confetti animation using an external JS library when all tasks are completed.
