A Simple Hash Table in JavaScript
/*HASH TABLE - a dictionary/hash map data structure for storing key/value pairs. Finding
an entry in a hash table takes O(1) constant time(same for 10 as 1 billion items). Whereas
finding an item via binary search takes time proportional to the logarithm of
the item in the list O(logn). Finding an item in a regular old list takes time proportional to
the length of the list O(n). Very slow. Hash Tables = very fast */

Array iteration methods summarized

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it much simpler to think about both the old list and the new one, what they contain, and
