In Node Web Development [Packt], the author uses a Fibonacci algorithm as an example that could block the event loop. It outlines one solution where the calculation is split into callbacks dispatched through the event loop,…

在 Packt 出版的《Node Web Development》中，作者用斐波那契算法作为可能会阻塞 event loop 的例子。书中概述了一种解决方案，即把计算拆分成通过 event loop 派发的 callbacks，……
