How does scope work in JavaScript?

Can you explain how scope works in JavaScript?

Sure! In JavaScript, scope refers to the visibility of variables. There are two main types: global and local scope.

What is the difference between global and local scope?

Global scope means a variable is accessible from anywhere in the code, while local scope means it's only accessible within a specific function.

Can you give me an example of local scope?

Of course! If you declare a variable inside a function, it can only be used within that function. For example:

function myFunction() {
    let localVar = 'I am local';
    console.log(localVar);
}
myFunction(); // Outputs: I am local
console.log(localVar); // ReferenceError: localVar is not defined
