What are some use cases for anonymous functions?

Anonymous functions, or lambda functions, are often used in programming for short, throwaway functions. They are useful in scenarios like callbacks, event handling, and functional programming.

Can you give me an example of using an anonymous function in JavaScript?

Sure! In JavaScript, you can use an anonymous function as a callback in array methods like map or filter. For example: const squares = numbers.map(function(num) { return num * num; });.

What about in Python? How are they used there?

In Python, you can use the lambda keyword to create anonymous functions. For example: squares = list(map(lambda x: x * x, numbers)).

Are there any downsides to using anonymous functions?

Yes, while they are convenient, anonymous functions can make code harder to read and debug, especially if overused or used in complex scenarios.
