Curious about how JavaScript handles variables in functions? In this quick 30-second video, we'll uncover the magic of lexical scoping and make it super easy to understand!

Imagine we have a function called 'greet()', and inside it, we've got a variable named 'name' with the value "Alice".

Now, here's the cool part: we also have another function called 'sayHello()' nested inside 'greet()'.

And guess what?

'sayHello()' can access the 'name' variable from its parent function!

So when we call 'greet()', it triggers 'sayHello()', and boom! The console says, "Hello, Alice!"

It's all thanks to the power of lexical scoping, where inner functions can grab variables from their outer functions effortlessly.
