This term means that yield* gen iterates over the generator gen and transparently forwards its yields outside.Thu, 25 Jun 2026 12:20:00 GMThttps://javascript.info/async-iterators-generatorsRecall generators Now let’s recall generators, as they allow to make iteration code much shorter. Most of the time, when we’d like to make an iterable, we’ll use generators. For sheer simplicity, omitting some important stuff, they are “functions that generate (yield) values”. They are explained in detail in the chapter Generators. Generators are labelled with function* (note the ...Sun, 21 Jun 2026 19:13:00 GMThttps://tr.javascript.info/generatorsThe special yield* directive in the example is responsible for the composition. It delegates the execution to another generator. Or, to say it simple, it runs generators and transparently forwards their yields outside, as if they were done by the calling generator itself. The result is the same as if we inlined the code from nested generators:Thu, 11 Jun 2026 05:20:00 GMThttps://tr.javascript.info/async-iterators-generatorsThen we yield all commits received, and when they finish – the next while(url) iteration will trigger, making one more request. An example of use (shows commit authors in console): ... That’s just what we wanted. The internal mechanics of paginated requests is invisible from the outside. For us it’s just an async generator that returns ...Thu, 28 May 2026 10:51:00 GMThttps://javascript.info/nullish-coalescing-operatorThe nullish coalescing operator is written as two question marks ??. As it treats null and undefined similarly, we’ll use a special term here, in this article. For brevity, we’ll say that a value is “defined” when it’s neither null nor undefined. The result of a ?? b is: if a is defined, then a, if a isn’t defined, then b. In other words, ?? returns the first argument if it’s not ...Tue, 23 Jun 2026 14:03:00 GMThttps://zh.javascript.info/generatorsyield* 指令将执行 委托 给另一个 generator。 这个术语意味着 yield* gen 在 generator gen 上进行迭代，并将其产出（yield）的值透明地（transparently）转发到外部。 就好像这些值就是由外部的 generator yield 的一样。 执行结果与我们内联嵌套 generator 中的代码获得的结果相同：Thu, 25 Jun 2026 05:18:00 GMThttps://es.javascript.info/generatorsLa directiva yield* delega la ejecución a otro generador. Este término significa que yield* gen itera sobre el generador gen y reenvía de forma transparente sus yields al exterior. Como si los valores fueran proporcionados por el generador externo. El resultado es el mismo que si insertamos el código de los generadores anidados:Thu, 25 Jun 2026 12:34:00 GMThttps://javascript.info/regular-expressionsRegular expressions is a powerful way of doing search and replace in strings.Tue, 23 Jun 2026 10:06:00 GMThttps://cors.javascript.info/article/modules-intro/scopes/cors.javascript.infoThu, 18 Jun 2026 18:33:00 GMThttps://cors.javascript.info/article/js-animation/move/cors.javascript.infoSun, 14 Dec 2025 05:17:00 GMT
