We often hear that JavaScript functions are first-class functions, meaning both functions and objects are treated by the language as the same thing. In practical terms, a function can be stored as a variable, inside an array or an object, as well as it can be passed as an argument or be returned by another function. That makes functions “first-class citizens” in JavaScript.
