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 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 are Value Objects: they implement `equals()`\n * and `hashCode()`.\n */\nfunction 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 (\n typeof valueA.valueOf === 'function' &&\n typeof valueB.valueOf === 'function'\n ) {\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 return !!(\n isValueObject(valueA) &&\n isValueObject(valueB) &&\n valueA.equals(valueB)\n );\n}\n\nvar imul =\n typeof Math.imul === 'function' && Math.imul(0xffffffff, 2) === -2\n ?
