Chrome 63, released in December, included async iterators and the associated for-await-of syntax. As the feature is now official in V8 6.3, it’s also likely to land in the upcoming Node.js 10 release this April. In light of its imminent availability in Node.js, I figured that it was time to start exploring the real-world potential of async iterators on the backend. Combining the async and await keywords with generator functions provides an elegant way to express streaming operations in modern JavaScript applications.
