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 the 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 implement `equals` and `hashCode`. + * + */ + function is(valueA, valueB) { + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + if (typeof valueA.valueOf === 'function' && + typeof valueB.valueOf === 'function') { + valueA = valueA.valueOf(); + valueB = valueB.valueOf(); + if (valueA === valueB || (valueA !== valueA && valueB !== valueB)) { + return true; + } + if (!valueA || !valueB) { + return false; + } + } + if (typeof valueA.equals === 'function' && + typeof valueB.equals === 'function' && + valueA.equals(valueB)) { + return true; + } + return false; + } + + function deepEqual(a, b) { + if (a === b) { + return true; + } + + if ( + !isIterable(b) || + a.size !== undefined && b.size !== undefined && a.size !== b.size || + a.__hash !== undefined && b.__hash !== undefined && a.__hash !== b.__hash || + isKeyed(a) !== isKeyed(b) || + isIndexed(a) !== isIndexed(b) || + isOrdered(a) !== isOrdered(b) + ) { + return false; + } + + if (a.size === 0 && b.size === 0) { + return true; + } + + var notAssociative = !isAssociative(a); + + if (isOrdered(a)) { + var entries = a.entries(); + return b.every(function(v, k) { + var entry = entries.next().value; + return entry && is(entry[1], v) && (notAssociative || is(entry[0], k)); + }) && entries.next().done; + } + + var flipped = false; + + if (a.size === undefined) { + if (b.size === undefined) { + if (typeof a.cacheResult === 'function') { + a.cacheResult(); + } + } else { + flipped = true; + var _ = a; + a = b; + b = _; + } + } + + var allEqual = true; + var bSize = b.__iterate(function(v, k) { + if (notAssociative ? !a.has(v) : + flipped ? !is(v, a.get(k, NOT_SET)) : !is(a.get(k, NOT_SET), v)) { + allEqual = false; + return false; + } + }); + + return allEqual && a.size === bSize; + } + + createClass(Repeat, IndexedSeq); + + function Repeat(value, times) { + if (!(this instanceof Repeat)) { + return new Repeat(value, times); + } + this._value = value; + this.size = times === undefined ?
