How do I use variables in scope?

Can you explain how to use variables in scope?

Sure! Variables in scope refer to the accessibility of variables within certain parts of your code. Do you have a specific programming language in mind?

I'm working with JavaScript. How does scoping work there?

In JavaScript, there are two main types of scope: global and local. Global variables are accessible anywhere, while local variables are only accessible within the function they are defined in.

What about block scope? I heard about it in ES6.

Great question! In ES6, block scope was introduced with let and const. Variables declared with these keywords are only accessible within the block they are defined in, such as within an if statement or a loop.

Can you give me an example of block scope?

Absolutely! Here's a simple example:

if (true) {
    let blockScopedVar = 'I am block scoped';
    console.log(blockScopedVar); // This will log the variable
}
console.log(blockScopedVar); // This will throw an error
