How to Choose the Right Project as a Beginner
Start simple, then level up.
| Skill Level | Project Type | Example |
|---|---|---|
| Beginner | DOM manipulation | To-Do App |
| Intermediate | API integration | Weather App |
| Advanced | Firebase / Authentication | Chat App |
👉 Pro Tip: Don’t just copy tutorials — customize each project by adding new features or styling. That’s how you truly learn JavaScript.
Project #1: To-Do List App
🎯 Goal: Learn DOM manipulation and event handling.
This classic project teaches you how to add, delete, and mark tasks as complete using JavaScript.

localStorage
Core Concepts:
const input = document.querySelector('#taskInput');
const list = document.querySelector('#taskList');
function addTask() {
const li = document.createElement('li');
li.textContent = input.value;
list.appendChild(li);
input.value = '';
}
💡 Upgrade Idea: Add a dark mode toggle or task filtering system.
