Скачать или смотреть Anonymous Functions Explained: A Simple Guide

Imagine a function without a name.
That's essentially what an anonymous function is. It's a piece of code that performs a specific task but doesn't have a label you can call it by.

Why use them?

Short, simple tasks: When you need to do something quickly and don't want to create a full-fledged function.
Passing functions as arguments: Many functions in programming accept other functions as input. Anonymous functions are handy for this.
Creating callbacks: These are functions that are executed after something else finishes, and anonymous functions are often used for this.
Think of it like a one-time use tool. You use it for a specific job, and then you don't need it again.
