Micron Benchmark For process.env performance

This is a benchmark to analize the performance between using only one process.env or multiple each time.

Motivation

In this benchmark we measure the performance variation using process.env in this two ways:

function pwd(){
    return process.env.PWD;
}

vs

const PWD = process.env.PWD
function pwd(){
    return PWD;
}

Results

As expected using the env variable in a const is the best way to use process.env, this is because process.env make a SO call so if we use this always it'll consume some time.
