/**
|
||
* An extension of the "same-value" algorithm as [described for use by ES6 Map
|
||
* and Set](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#Key_equality)
|
||
*
|
||
* NaN is considered the same as NaN, however -0 and 0 are considered the same
|
||
* value, which is different from the algorithm described by
|
||
* [`Object.is`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/is).
|
||
*
|
||
* This is extended further to allow Objects to describe the values they
|
||
* represent, by way of `valueOf` or `equals` (and `hashCode`).
|
||
*
|
||
* Note: because of this extension, the key equality of Immutable.Map and the
|
||
* value equality of Immutable.Set will differ from ES6 Map and Set.
|
||
*
|
||
* ### Defining custom values
|
||
*
|
||
* The easiest way to describe the value an object represents is by implementing
|
||
* `valueOf`. For example, `Date` represents a value by returning a unix
|
||
* timestamp for `valueOf`:
|
||
*
|
||
* var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...
|
||
* var date2 = new Date(1234567890000);
|
||
* date1.valueOf(); // 1234567890000
|
||
* assert( date1 !== date2 );
|
||
* assert( Immutable.is( date1, date2 ) );
|
||
*
|
||
* Note: overriding `valueOf` may have other implications if you use this object
|
||
* where JavaScript expects a primitive, such as implicit string coercion.
|
||
*
|
||
* For more complex types, especially collections, implementing `valueOf` may
|
||
* not be performant. An alternative is to implement `equals` and `hashCode`.
|
||
*
|
||
* `equals` takes another object, presumably of similar type, and returns true
|
||
* if it is equal. Equality is symmetrical, so the same result should be
|
||
* returned if this and the argument are flipped.
|
||
*
|
||
* assert( a.equals(b) === b.equals(a) );
|
||
*
|
||
* `hashCode` returns a 32bit integer number representing the object which will
|
||
* be used to determine how to store the value object in a Map or Set. You must
|
||
* provide both or neither methods, one must not exist without the other.
|
||
*
|
||
* Also, an important relationship between these methods must be upheld: if two
|
||
* values are equal, they *must* return the same hashCode. If the values are not
|
||
* equal, they might have the same hashCode; this is called a hash collision,
|
||
* and while undesirable for performance reasons, it is acceptable.
|
||
*
|
||
* if (a.equals(b)) {
|
||
* assert( a.hashCode() === b.hashCode() );
|
||
* }
|
||
*
|
||
* All Immutable collections are Value Objects: they implement `equals()`
|
||
* and `hashCode()`.
