First-class functions are functions that can be treated like any other value. You can pass them to functions as arguments, return them from functions, and save them in variables. In this episode, we talk about why they are important for functional programming and what features we require of ...
In this chapter, we will explore Scala’s use of first-class functions, higher-order functions, and the use of function literals to easily create or pass logical expressions anywhere a regular function could be used. Function Types and Values The type of a function is a simple grouping of ...
In computer science, a programming language is said to havefirst-class functionsif it treats functions as first-class citizens. Specifically, this means the language supports passing functions as arguments to other functions, returning them as the values from other functions, and assigning them to v...

is said to support first-class functions if it treats functions as first-class objects. Specifically, this means that functions can be created during the execution of a program, stored in data structures, passed as arguments to other functions, and returned as the values of other functions....
