🛠 Prerequisites
- •A modern web browser (Chrome, Firefox, Edge)
- •A code editor (VS Code recommended)
- •Basic computer literacy
- •Node.js (for Modules 14+)
🚀 Getting Started
- •Start with Module 1 - JavaScript Fundamentals
- •Open the
README.md file in each topic folder
- •Study the concepts thoroughly
- •Check
examples.js to see practical implementations
- •Complete
exercises.js to test your knowledge
- •Move to the next topic once you're comfortable
💡 Tips for Success
- •Don't skip topics - Each concept builds on previous ones
- •Type the code yourself - Don't just copy-paste
- •Experiment - Modify examples and see what happens
- •Use DevTools - Practice in browser console
- •Be patient - Some concepts take time to understand
- •Build projects - Apply what you learn in real projects
