/**
* Immutable data encourages pure functions (data-in, data-out) and lends itself
* to much simpler application development and enabling techniques from
* functional programming such as lazy evaluation.
*
* While designed to bring these powerful functional concepts to JavaScript, it
* presents an Object-Oriented API familiar to Javascript engineers and closely
* mirroring that of Array, Map, and Set. It is easy and efficient to convert to
* and from plain Javascript types.
*
* ## How to read these docs
*
* In order to better explain what kinds of values the Immutable.js API expects
* and produces, this documentation is presented in a statically typed dialect of
* JavaScript (like [Flow][] or [TypeScript][]). You *don't need* to use these
* type checking tools in order to use Immutable.js, however becoming familiar
* with their syntax will help you get a deeper understanding of this API.
*
* **A few examples and how to read them.**
*
* All methods describe the kinds of data they accept and the kinds of data
* they return. For example a function which accepts two numbers and returns
* a number would look like this:
*
* ```js
* sum(first: number, second: number): number
* ```
*
* Sometimes, methods can accept different kinds of data or return different
* kinds of data, and this is described with a *type variable*, which is
* typically in all-caps. For example, a function which always returns the same
* kind of data it was provided would look like this:
*
* ```js
* identity<T>(value: T): T
* ```
*
* Type variables are defined with classes and referred to in methods. For
* example, a class that holds onto a value for you might look like this:
*
* ```js
* class Box<T> {
* constructor(value: T)
* getValue(): T
* }
* ```
*
* In order to manipulate Immutable data, methods that we're used to affecting
* a Collection instead return a new Collection of the same type. The type
* `this` refers to the same kind of class. For example, a List which returns
* new Lists when you `push` a value onto it might look like:
*
* ```js
* class List<T> {
* push(value: T): this
* }
* ```
*
* Many methods in Immutable.js accept values which implement the JavaScript
* [Iterable][] protocol, and might appear like `Iterable<string>` for something
* which represents sequence of strings. Typically in JavaScript we use plain
* Arrays (`[]`) when an Iterable is expected, but also all of the Immutable.js
* collections are iterable themselves!
*
* For example, to get a value deep within a structure of data, we might use
* `getIn` which expects an `Iterable` path:
*
* ```
* getIn(path: Iterable<string | number>): any
* ```
*
* To use this method, we could pass an array: `data.getIn([ "key", 2 ])`.
*
*
* Note: All examples are presented in the modern [ES2015][] version of
* JavaScript. Use tools like Babel to support older browsers.
*
* For example:
*
* ```js
* // ES2015
* const mappedFoo = foo.map(x => x * x);
* // ES5
* var mappedFoo = foo.map(function (x) { return x * x; });
* ```

* ```
*
* This is most commonly used to call methods on collections within a

* `update` and `push` can be used together:
*
* <!-- runkit:activate
* { "preamble": "const { Map, List } = require('immutable');" }
* -->
* ```js
* const aMap = Map({ nestedList: List([ 1, 2, 3 ]) })

* // Map { "nestedList": List [ 1, 2, 3, 4 ] }
* ```
*

* function when the value at the key does not exist in the Map.
*
* <!-- runkit:activate

* const newMap = aMap.update('noKey', 'no value', value => value + value)
* // Map { "key": "value", "noKey": "no valueno value" }
* ```
*
* However, if the `updater` function returns the same value it was called
* with, then no change will occur. This is still true if `notSetValue`
* is provided.
*
* <!-- runkit:activate
* { "preamble": "const { Map } = require('immutable');" }
* -->
* ```js
* const aMap = Map({ apples: 10 })
* const newMap = aMap.update('oranges', 0, val => val)
* // Map { "apples": 10 }
* assert.strictEqual(newMap, map);
* ```
*
* For code using ES2015 or later, using `notSetValue` is discourged in
* favor of function parameter default values. This helps to avoid any
* potential confusion with identify functions as described above.
*
* The previous example behaves differently when written with default values:
*
* <!-- runkit:activate
* { "preamble": "const { Map } = require('immutable');" }
* -->
* ```js
* const aMap = Map({ apples: 10 })
* const newMap = aMap.update('oranges', (val = 0) => val)
* // Map { "apples": 10, "oranges": 0 }
* ```
*
* If no key is provided, then the `updater` function return value is
* returned as well.
*
* <!-- runkit:activate
* { "preamble": "const { Map } = require('immutable');" }
* -->
* ```js
* const aMap = Map({ key: 'value' })
* const result = aMap.update(aMap => aMap.get('key'))
* // "value"
* ```
*
* This can be very useful as a way to "chain" a normal function into a
* sequence of methods. RxJS calls this "let" and lodash calls it "thru".
*
* For example, to sum the values in a Map
*
* <!-- runkit:activate
* { "preamble": "const { Map } = require('immutable');" }
* -->
* ```js
* function sum(collection) {
* return collection.reduce((sum, x) => sum + x, 0)
