JavaScript Autoboxing Explained 🔥 | How Primitives Use Methods Like Objects

Описание: Ever wondered how primitive values like strings or numbers in JavaScript can use methods like an object? 🤔
This video explains Autoboxing in JavaScript — the hidden process where JavaScript automatically wraps a primitive value (like a string, number, or boolean) into its corresponding object type (String, Number, Boolean) so you can call methods on it! 💡

Discover how "hello".toUpperCase() works magically even though "hello" isn’t technically an object.
You’ll learn:
✅ What Autoboxing and Unboxing mean in JavaScript
✅ How the JavaScript engine temporarily converts primitive types into objects
✅ Difference between primitive values and object wrappers
✅ Common pitfalls and performance implications
✅ Why this feature matters in interviews and real-world JavaScript projects

This short is perfect for:
💻 JavaScript beginners who want to understand the language deeply
🚀 Frontend developers mastering JavaScript fundamentals
🎯 Interview preparation for topics like JS data types, type conversion, and object wrappers

By the end, you’ll understand how JavaScript’s behind-the-scenes behavior makes primitives feel like objects — a must-know for every JavaScript developer!
