The Generator uses the new keyword, yield, to pause and return a value from a generator function. This behavior is opposed to traditional JavaScript functions, which execute fully and return a single value with a return statement. In JavaScript, a generator is like a traditional function that produces an iterable Generator object. Generators in JavascriptĪ generator is a function that can produce many output values, and may be paused and resumed. Start enjoying your debugging experience - start using OpenReplay for free.

This is a basic idea ofIterables andIterators` for more reading, refer here. And as a result, our above LeapYear type is an Iterable too. I prefer the first implementation.As stated earlier, Iterable's are JavaScript structures with the erator() method, likeArray, String, Set. In this exercise, it doesn’t improve the maintainability very much. This technique is good to know but if we want to use it in a real project where there are several developers, we should have a dev-exchange meeting for it. I didn’t understand how it worked at the first glance. Which code do you prefer? I guess not many developers know erator and thus the second implementation is less readable. I didn’t have a good idea of how to use Symbol but this is a good example. do something with iteratorResult.value

If (ANSWER != currentString) Conclusionīy using erator, we can extract an iterator object from an array. Return ONE_TWO_THREE Ĭonst actualStringArray: StringNumType =

Type StringNumType = typeof ONE_TWO_THREE Conclusion Implementation without eratorįirstly, let’s implement it without erator.How is erator is defined in the interface.
