What are the different types of scope in programming?

In programming, scope refers to the visibility of variables. The main types are global, local, and block scope.

Can you explain global scope with an example?

Sure! Global scope means a variable is accessible from anywhere in the code. For example, if you declare a variable outside of any function, it has global scope.

What about local scope?

Local scope means a variable is only accessible within the function or block where it is defined. For instance, a variable declared inside a function cannot be accessed outside of it.

And what is block scope?

Block scope is similar to local scope but applies to blocks defined by curly braces, like in loops or conditionals. Variables declared with 'let' or 'const' in a block are not accessible outside that block.
