Create a Simple To-Do List Application

Help users stay organized by building a sleek to-do list app with task creation, completion tracking, and basic CRUD functionality — perfect for beginners learning JavaScript.

Why Build a Simple To-Do List App?

A to-do list app is a fundamental project that introduces developers to concepts like event handling, CRUD operations (Create, Read, Update, Delete), and local storage. It's a must-build project for understanding dynamic content management.

Core Features of the To-Do List App

The app should provide users with a simple, clean way to add, mark, edit, and delete tasks — with optional persistence using local storage.

Key Features to Implement

Add New Tasks

Allow users to input new tasks easily and display them immediately in a task list.

Mark Tasks as Complete

Enable users to mark tasks as done by clicking on them or checking a box.

Edit or Delete Tasks

Provide options to modify or remove tasks from the list quickly.

Persist Tasks with Local Storage

Save the task list in local storage so tasks remain even after page refreshes (optional enhancement).

How the Simple To-Do List App Works

Users can add tasks through an input field. Each task appears in a list with options to mark it complete, edit, or delete. Optionally, tasks can be stored locally for persistence across sessions.

  • User enters a task in an input box and clicks Add.
  • The new task appears instantly in the task list.
  • Completed tasks are visually distinguished (e.g., strikethrough).
  • Tasks can be edited or deleted individually.
  • All tasks are optionally stored in localStorage for persistence.
Recommended Technology Stack

Frontend

HTML5, CSS3, and Vanilla JavaScript

Task Persistence

Browser localStorage API for saving tasks locally

Optional Libraries

Animate.css for adding simple animations to task events

Hosting

Step-by-Step Development Guide

1. Set Up Basic Structure

Create the HTML structure with an input field, add button, and task display area.

2. Handle Task Addition

Use JavaScript event listeners to capture input and dynamically add new tasks to the list.

3. Implement Complete, Edit, Delete Functions

Enable marking tasks done, editing tasks, and removing them from the list.

4. Save Tasks in Local Storage

Store the task list in localStorage and load it when the page reloads.

5. Make It Responsive and Stylish

Use CSS to style the app for mobile and desktop users with clean, modern design.
