Iterator.prototype.chunks ( [ _chunkSize_ ] )

+

This method performs the following steps when called:

+ + 1. Let _O_ be the *this* value. + 1. If _O_ is not an Object, throw a *TypeError* exception. + 1. If _chunkSize_ is not present, set _chunkSize_ to *2*𝔽. + 1. If _chunkSize_ is not an integral Number in the inclusive interval from *1*𝔽 to 𝔽(232 - 1), throw a *RangeError* exception. + 1. Let _iterated_ be ? GetIteratorDirect(_O_). + 1. Let _closure_ be a new Abstract Closure with no parameters that captures _iterated_ and _chunkSize_ and performs the following steps when called: + 1. Let _buffer_ be a new empty List. + 1. Repeat, + 1. Let _value_ be ? IteratorStepValue(_iterated_). + 1. If _value_ is ~done~, return *undefined*. + 1. Append _value_ to _buffer_. + 1. If the number of elements in _buffer_ is ℝ(_chunkSize_), then + 1. Let _completion_ be Completion(Yield(CreateArrayFromList(_buffer_))). + 1. IfAbruptCloseIterator(_completion_, _iterated_). + 1. Set _buffer_ to a new empty List. + 1. Let _result_ be CreateIteratorFromClosure(_closure_, *"Iterator Helper"*, %IteratorHelperPrototype%, « [[UnderlyingIterators]] »). + 1. Set _result_.[[UnderlyingIterators]] to « _iterated_ ». + 1. Return _result_. + + + + +

Iterator.prototype.windows ( [ _windowSize_ ] )

+

This method performs the following steps when called:

+ + 1. Let _O_ be the *this* value. + 1. If _O_ is not an Object, throw a *TypeError* exception. + 1. If _windowSize_ is not present, set _windowSize_ to *2*𝔽. + 1. If _windowSize_ is not an integral Number in the inclusive interval from *1*𝔽 to 𝔽(232 - 1), throw a *RangeError* exception. + 1. Let _iterated_ be ? GetIteratorDirect(_O_). + 1. Let _closure_ be a new Abstract Closure with no parameters that captures _iterated_ and _windowSize_ and performs the following steps when called: + 1. Let _buffer_ be a new empty List. + 1. Repeat, + 1. Let _value_ be ? IteratorStepValue(_iterated_). + 1. If _value_ is ~done~, return *undefined*. + 1. Append _value_ to _buffer_. + 1. If the number of elements in _buffer_ is ℝ(_windowSize_), then + 1. Let _completion_ be Completion(Yield(CreateArrayFromList(_buffer_))). + 1. IfAbruptCloseIterator(_completion_, _iterated_). + 1. Remove the first element from _buffer_. + 1. Let _result_ be CreateIteratorFromClosure(_closure_, *"Iterator Helper"*, %IteratorHelperPrototype%, « [[UnderlyingIterators]] »). + 1. Set _result_.[[UnderlyingIterators]] to « _iterated_ ». + 1. Return _result_. + +
