A language has first-class functions , when functions can be treated as values that can be passed, manipulated, returned ... ie it is possible to operate functions. This concept is an attribute of language, or she has or does not have it.

High order function is a function that receives or returns a function. Only a high-order function can be defined if the language has first-class functions , since functions are "passable" . This concept is an attribute of the function, or it is or is not.

EDIT

Languages that do not have first class functions, such as C, still allow you to create high order functions using function pointers.

Javascript is a language that has first-class functions, that is, it is possible to pass, return and operate functions.
