First-class functions, Closures and Higher-order functions

First-Class Functions In computer science, a programming language is said to have first-class functions if it treats functions as first-class citizens Higher-Order Functions In mathematics and computer science, a higher-order function is a function that does at least one of the following: takes one or more functions as arguments, and returns a function as its result. All other functions are first-order functions. In mathematics, higher-order functions are also termed operators or functionals.
