Introduction:
Welcome to the comprehensive guide to learning JavaScript! Whether you're a beginner or looking to refresh your skills, this roadmap will guide you through essential JavaScript concepts step by step. Let's dive in!

Week 1: Building Foundations

Day 1: JavaScript Basics

Set up your development environment with Node.js and Visual Studio Code.
Learn about JavaScript syntax, variables (var, let, const), and basic data types (string, number, boolean).
Write and execute a simple "Hello, World!" program.

Day 2: Functions and Control Structures

Understand functions: declaration, parameters, return values, and function expressions.
Explore control structures such as if statements, switch statements, and loops (for, while).
Practice writing functions and using control structures to solve simple problems.

Day 3: Arrays and Objects

Dive into arrays: creation, accessing elements, adding/removing elements, and array methods (forEach, map, filter).
Learn about JavaScript objects: creating object literals, accessing properties, and methods.
Complete hands-on exercises with arrays and objects.

Day 4: Scope and Closures

Understand variable scope: global scope, function scope, and block scope.
Explore closures: definition, how they work, and practical examples.
Write functions to demonstrate scope and closures.

Day 5: DOM Manipulation

Understand the Document Object Model (DOM) and its structure.
Learn how to select elements using querySelector and querySelectorAll.
Explore modifying elements, changing text/content, styles, and attributes.
Add event listeners to respond to user interactions.

Week 2: Intermediate Concepts and Project Building

Day 6: Asynchronous JavaScript

Learn asynchronous programming concepts: callbacks, promises, and async/await.
Handle asynchronous tasks with setTimeout(), setInterval(), and fetching data from APIs.

Day 7: Error Handling and Debugging

Understand error handling in JavaScript: try...catch blocks, throwing and catching errors.
Explore debugging techniques using browser developer tools such as Chrome DevTools.
Debug code snippets and identify common errors.

Day 8: ES6+ Features

Discover modern JavaScript features introduced in ES6 and beyond: arrow functions, template literals, destructuring, and spread/rest operators.
Rewrite previous code using these features to practice.

Day 9: Working with Browser APIs

Explore commonly used browser APIs such as Local Storage, Fetch API for making HTTP requests, and Geolocation API.
Build a small project that utilizes one or more of these APIs.

Day 10: Introduction to Frameworks

Explore popular JavaScript frameworks/libraries: React.js, Vue.js, Angular.
Choose one framework to learn more about and complete a basic tutorial or documentation reading.

Day 11-12: Mini Project

Dedicate these two days to working on a mini project of your choice (e.g., to-do list app, weather app, or simple game). Apply what you've learned so far and challenge yourself.

Day 13-14: Review and Planning Ahead
