What are some real-world uses of closures in programming?
Closures are often used for data encapsulation, creating private variables, and maintaining state in asynchronous programming.
Can you give me an example of how closures are used in JavaScript?
Sure! In JavaScript, closures are used in functions that return other functions, allowing the inner function to access the outer function's scope.
Why are closures important in functional programming?
Closures are crucial in functional programming as they enable higher-order functions and help manage state without global variables.
Are there any performance considerations when using closures?
Yes, closures can lead to increased memory usage since they maintain references to their outer scope, which can affect performance.
