What is the primary purpose of a closure in programming?

• To execute code asynchronously

• To improve the performance of a program

• To simplify the syntax of a function

• To encapsulate data and functions together

In what scenario would using a closure be most beneficial?

• When you want to write a recursive function

• When you want to execute a function immediately

• When you need to create a new variable scope

• When you need to maintain state between function calls

How do closures help in managing state in JavaScript?

• By using local variables only

• By allowing functions to remember their lexical environment

• By creating global variables

• By preventing any state changes

Which of the following is NOT a benefit of using closures?

• Ability to create factory functions

• Improved code readability

• Enhanced data privacy

• Increased execution speed

Which of the following best describes how closures work?

• They allow a function to modify its own code

• They restrict a function from accessing any variables

• They enable a function to access variables from an outer function's scope

• They allow a function to access variables from its own scope only
