Lambdas and higher-order functions

Although we have already discussed higher-order functions earlier in this book, in this section, we aim to explore additional related concepts in more detail. Specifically, we will focus on understanding how lambdas, receivers, and collections play a role in enhancing the flexibility and efficiency of higher-order functions in Kotlin.

Let’s start with what we already know. We know that these are functions that can accept other functions as parameters or return them as results, allowing us to write more reusable and modular code.

In the world of programming, functions are essential because they allow us to abstract common behaviors and make them reusable across different parts of our code. This approach provides greater flexibility, as we can pass functions as arguments to other functions, enabling us to dynamically adjust their behavior. By doing so, we effectively customize the functionality at runtime, adapting it to specific scenarios...
