🛠 Issue Title: Add Advanced JavaScript Topics to Enhance Learning Resources

📌 Description:
The current JavaScript section on the devNotes website covers essential and intermediate concepts well. However, to support users aiming to deepen their understanding and transition to advanced development, it's important to include more advanced JavaScript topics.

💡 Suggested Additions:

• Closures and lexical environment
• Event Loop and Microtasks
• Prototypes and Prototype Chain
• this, call, apply, bind
• Currying and Partial Application
• Debounce and Throttle
• JavaScript Design Patterns (Module, Singleton, Observer, etc.)
• Memory Management and Garbage Collection
• Shadow DOM and Custom Elements (Web Components)
• Advanced Asynchronous Patterns (Promise.all, async/await with error handling, etc.)

✅ Benefits:

• Improves the depth of content available on the platform
• Helps learners build a strong foundation before moving to frameworks like React, Vue, etc.
