What is the primary purpose of a closure in programming?

• To simplify syntax

• To reduce memory usage

• To increase the speed of code execution

• To encapsulate data and functions together

Which of the following best describes how closures work?

• They enable functions to access variables from an outer scope

• They make functions independent of any scope

• They allow functions to access variables from their own scope only

• They restrict functions to use only global variables

In which scenario is a closure most useful?

• When you want to use less memory

• When you need to execute code faster

• When you want to keep a variable private

• When you need to create a new variable

What is a common application of closures in JavaScript?

• To create private variables

• To define global constants

• To manage memory

• To optimize loops

How do closures contribute to data encapsulation?

• By allowing direct access to all variables

• By reducing the number of variables

• By hiding variables from the global scope

• By making all variables public
