Anonymous function

Hey kiddo, do you know what a function is? It's like a set of instructions that tells the computer what to do with some information. Now, an anonymous function is a type of function that doesn't have a name. Just like when you put on a Halloween mask, people don't know who you are, an anonymous function doesn't have a name that people can use to call it.

So, when can you use an anonymous function? Well, imagine you have a big program with lots of functions. Some of these functions are only used once in the program, and you don't want to clutter up your program with lots of extra functions that only get used once. Instead, you can create an anonymous function on the fly, right where you need it, and use it just that one time.

It's kind of like making a sandwich. If you're making a sandwich with lots of toppings, some of these toppings you only need a little bit of, like pickles. You don't want to have a whole jar of pickles just for this sandwich! So, you take a few pickles out of the jar, use them, and then you don't need them anymore.

That's what an anonymous function is like. It's a little bit of code that you only need once, so you don't give it a name. You just use it, and when you're done, you don't need it anymore.
