Best way to cache in Node.js

Question

I am trying to find the best caching solution for a node application. There are several modules that can manage this. Most popular: https://www.npmjs.com/package/node-cache

But I found that the answers are faster if I just save some results in a variable, for example:

var cache = ["Kosonsoy","Pandean","Ḩadīdah","Chirilagua","Chattanooga","Hebi","Péruwelz","Pul-e Khumrī"];

Then I can update this variable at a fixed interval, is it also classified as caching? Are there any known issues / issues for this method. Because it defiantly provides the fastest response times.
