Functions are treated like any other value: assignable to variables, passable as arguments, returnable from functions, storable in data structures, and typeof is 'function'.
A function statement is hoisted with its full body (callable before the line). A function expression is assigned to a variable (variable hoisted only, function body assigned at the line).
A function that takes a function as an argument, returns a function, or both. Examples include map, filter, reduce, compose, curry, and setTimeout.
