AsyncIterator:一个使用requestAnimationFrame批量处理大型数据集而不锁定UI的异步迭代器

AsyncIterator 一个使用requestAnimationFrame批量处理大型数据集而不锁定UI的异步迭代器。 // The dataset var myArr = []; // Number of operations per call var batchSize = 1000; // The actual processing method function work(item, index) { // Do something for each item } // Start iterator, it will return a promise var promise = asyncIterator(myArr, work, batchSize); // When promise is resolved, output results promise.done
