Chapter 8. Higher-order functions: lambdas as parameters and return values
This chapter covers
- Function types
- Higher-order functions and their use for structuring code
- Inline functions
- Non-local returns and labels
- Anonymous functions
You were introduced to lambdas in chapter 5, where we explored the general concept and the standard library functions that use lambdas. Lambdas are a great tool for building abstractions, and of course their power isn’t restricted to collections and other classes in the standard library. In this chapter, you’ll learn how to create higher-order functions—your own functions that take lambdas as arguments or return them. You’ll see how higher-order functions can help simplify your code, remove code duplication, ...
