What are some examples of closures in real-world apps?

Can you explain what closures are in programming?

Sure! Closures are functions that remember their outer variables and can access them even when the function is executed outside their original scope.

What are some real-world applications of closures?

Closures are used in various applications, such as event handlers in web development, data encapsulation in JavaScript, and maintaining state in asynchronous programming.

Can you give me a specific example of a closure in a web app?

Absolutely! In a web app, a closure can be used in a function that creates a counter. Each time you call the counter function, it retains the count value, allowing you to increment it without exposing the count variable globally.

How do closures help with memory management?

Closures help with memory management by allowing functions to maintain access to their scope without creating global variables, thus reducing memory leaks and improving performance.
