Provides an indexed, memoized view into the sequence. This will cache the result whenever the sequence is first iterated, so that subsequent iterations will access the same element objects.
Signature
Sequence.memoize = function() { /*...*/ }Sequence.memoize = function memoize() {
return new MemoizedSequence(this);
}| Name | Type(s) | Description |
|---|---|---|
| returns | ArrayLikeSequence | An indexed, memoized sequence containing this sequence's elements, cached after the first iteration. |
Examples
function createObject() { return new Object(); }
var plain = Lazy.generate(createObject, 10),
memoized = Lazy.generate(createObject, 10).memoize();
plain.toArray()[0] === plain.toArray()[0]; // => false
memoized.toArray()[0] === memoized.toArray()[0]; // => true
