🚀 Purpose

This repository is created as a personal JavaScript learning and reference resource.

It contains simple examples and practice programs covering JavaScript fundamentals as well as modern JavaScript concepts.

🛠️ Technologies

• JavaScript
• HTML
• DOM API
• Fetch API

▶️ How to Run

JavaScript Files

Most JavaScript files can be executed using Node.js:

node filename.js

Example:

node Basics/javascript_basics.js

DOM & Events

The DOM and Events examples require a browser.

Open the corresponding index.html file in a web browser to run them.

📌 Note

Some examples require a modern JavaScript environment because they use ES6+ features and modern APIs.
