 For example, a function can take other functions as arguments and/or produce a function as its return value.
 Such *fancy* functional techniques are powerful constructs available to you in JavaScript and other high-level languages like python, lisp, etc.

+We will now create two simple functions, `add_2` and `double`, and a higher order function called `map`. `map` will accept two arguments, `func` and `list` (its declaration will therefore begin `map(func,list)`), and return an array. `func` (the first argument) will be a function that will be applied to each of the elements in the array `list` (the second argument).

 // Define two simple functions
