本篇技术指南以 30-seconds-of-code 仓库中的 fibonacci.md为核心，讲解如何用 JavaScript 生成包含前 n 项的斐波那契数列数组，并对比迭代与递归两种实现方案的原理、性能差异与适用场景。读完本文，你将能够写出两种可复用的 fibonacci(n) 实现，理解递归基准情形（base ...

After @_Mr_Spike_ told me it takes 3 weeks to generate the 50th Fibonacci number using recursion, I created this script to check if I can do better without recursion but with iteration. Damn fast.

I originally wrote this solution during my full-stack development bootcamp while completing a JavaScript exercise involving Fibonacci numbers. Generator functions were not part of the bootcamp ...
