INITIALIZE
==============
sudo npm i -g npm       // update npm
sudo npm update -g      // update packages
npm init                // initiate project

INSTALATION
==============
sudo npm i --save benchmark
sudo npm i --save lodash
sudo npm i --save platform

RUN TEST
===================
node test.js

RESULT
===================
RegExp#test x 12,930,284 ops/sec ±2.44% (62 runs sampled)
String#indexOf x 20,757,535 ops/sec ±2.82% (62 runs sampled)
String#match x 7,125,209 ops/sec ±8.82% (54 runs sampled)
Fastest is String#indexOf
