What are scope and return statements in programming?

Scope refers to the visibility of variables in different parts of your code, while return statements are used to exit a function and send a value back.

Can you explain the different types of scope?

Sure! There are mainly three types of scope: global scope, local scope, and block scope. Global variables are accessible anywhere, local variables are accessible only within the function they are defined, and block scope is limited to the block in which it is defined.

How do return statements work in functions?

Return statements end the execution of a function and can return a value to the caller. If no value is specified, it returns undefined.

Can you give an example of a function with a return statement?

Absolutely! Here's a simple example: function add(a, b) { return a + b; }. This function takes two parameters and returns their sum.
