For example, `Date` represents a value by returning a unix\n * timestamp for `valueOf`:\n *\n * var date1 = new Date(1234567890000); // Fri Feb 13 2009 ...\n * var date2 = new Date(1234567890000);\n * date1.valueOf(); // 1234567890000\n * assert( date1 !== date2 );\n * assert( Immutable.is( date1, date2 ) );\n *\n * Note: overriding `valueOf` may have other implications if you use this object\n * where JavaScript expects a primitive, such as implicit string coercion.\n *\n * For more complex types, especially collections, implementing `valueOf` may\n * not be performant. An alternative is to implement `equals` and `hashCode`.\n *\n * `equals` takes another object, presumably of similar type, and returns true\n * if the it is equal. Equality is symmetrical, so the same result should be\n * returned if this and the argument are flipped.\n *\n * assert( a.equals(b) === b.equals(a) );\n *\n * `hashCode` returns a 32bit integer number representing the object which will\n * be used to determine how to store the value object in a Map or Set. You must\n * provide both or neither methods, one must not exist without the other.\n *\n * Also, an important relationship between these methods must be upheld: if two\n * values are equal, they *must* return the same hashCode. If the values are not\n * equal, they might have the same hashCode; this is called a hash collision,\n * and while undesirable for performance reasons, it is acceptable.\n *\n * if (a.equals(b)) {\n * assert( a.hashCode() === b.hashCode() );\n * }\n *\n * All Immutable collections implement `equals` and `hashCode`.\n *\n */\n function is(valueA, valueB) {\n if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) {\n return true;\n }\n if (!valueA || !valueB) {\n return false;\n }\n if (typeof valueA.valueOf === 'function' &&\n typeof valueB.valueOf === 'function') {\n valueA = valueA.valueOf();\n valueB = valueB.valueOf();\n if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) {\n return true;\n }\n if (!valueA || !valueB) {\n return false;\n }\n }\n if (typeof valueA.equals === 'function' &&\n typeof valueB.equals === 'function' &&\n valueA.equals(valueB)) {\n return true;\n }\n return false;\n }\n\n function deepEqual(a, b) {\n if (a === b) {\n return true;\n }\n\n if (\n !isIterable(b) ||\n a.size !== undefined && b.size !== undefined && a.size !== b.size ||\n a.__hash !== undefined && b.__hash !== undefined && a.__hash !== b.__hash ||\n isKeyed(a) !== isKeyed(b) ||\n isIndexed(a) !== isIndexed(b) ||\n isOrdered(a) !== isOrdered(b)\n ) {\n return false;\n }\n\n if (a.size === 0 && b.size === 0) {\n return true;\n }\n\n var notAssociative = !isAssociative(a);\n\n if (isOrdered(a)) {\n var entries = a.entries();\n return b.every(function(v, k) {\n var entry = entries.next().value;\n return entry && is(entry[1], v) && (notAssociative || is(entry[0], k));\n }) && entries.next().done;\n }\n\n var flipped = false;\n\n if (a.size === undefined) {\n if (b.size === undefined) {\n if (typeof a.cacheResult === 'function') {\n a.cacheResult();\n }\n } else {\n flipped = true;\n var _ = a;\n a = b;\n b = _;\n }\n }\n\n var allEqual = true;\n var bSize = b.__iterate(function(v, k) {\n if (notAssociative ? !a.has(v) :\n flipped ? !is(v, a.get(k, NOT_SET)) : !is(a.get(k, NOT_SET), v)) {\n allEqual = false;\n return false;\n }\n });\n\n return allEqual && a.size === bSize;\n }\n\n createClass(Repeat, IndexedSeq);\n\n function Repeat(value, times) {\n if (!(this instanceof Repeat)) {\n return new Repeat(value, times);\n }\n this._value = value;\n this.size = times === undefined ?
