This kata is voulnerable to file read attack, you can simply require fs in node and then read the index file and have the kata solved for you.
I noticed cause when I'm stuck I just console.log this which shows index file is cached and fs is active.

const fs = require('fs');

fs.readFile('/home/codewarrior/index.js', 'utf8', (err, data) => {
  if (err) {
    console.error(err);
    return;
  }
  console.log(data);
});

When you get paid per line of code.

When your income depends on Line of Code.
