JavaScript Closures in 34 Seconds

What are JavaScript closures? 🤔 Closures are a powerful concept in JavaScript that allow an inner function to access variables from its parent function, even after the parent function has returned. Think of it as a backpack 🎒 where the inner function keeps variables from the outer function handy. Closures are essential for writing efficient, modular, and secure JavaScript code. In this short video, I’ll explain closures with a clear code example and break down how they work in just 34 seconds! Perfect for beginners 🚀.

🤔 All these jargons can sound tricky when explaining closures in JavaScript, but honestly, it’s not as complex as it seems once you practice! 💡 Run those nested functions a few times, and you’ll get the hang of how arguments are passed between them. 🔄

Funny enough, I almost never think about closures unless I need to explain them to someone—haha! 😄

🎯 If you’re prepping for an interview, this is a perfect time to refresh your memory on the theory and see how it works in action. 💻
