>>2950062Higher order functions are functions which operate on other functions. For example, the "map" function applies a given function to every elements of a list, array, tree, or any other similar data structure. The "reduce" function, on the other hand, uses a provided function to combine all of the elements of such a data structure into a final result, such as summing a list of numbers, or combing a list of lists into one giant list. There are many such functions, which can replace 99% of explicit loops you might write by hand, removing the possibility of something like incrementing the wrong variable, or flipping the comparison.
