node-fib's Introduction

node-fib

A little express server that gives you back whatever fibonacci number you ask for

Usage

node app.js &
curl localhost:3000/40

Replace 40 with whatever fibonacci number you want

Why?

To point out that implementation of whatever you're doing is far more important than which framework you're using, or whether you're using threads or an event loop to handle concurrency.

Is it any good?

Yes.
