Ooh this is a great use of do...while. I went with the less elegant nested if for mine 😅

## Part 1 (JavaScript)

const fs = require("fs");
const path = require("path");
const text = fs.readFileSync(path.join(__dirname) + "/input.txt", "utf8");
let output = text
.split("\n")
.map(d => calcFuelPerModule(d))
.reduce((acc, curr) => acc + curr, 0);
console.log(output);

function calcFuelPerModule(mass) {
return Math.floor(+mass / 3) - 2;
}


## Part 2 (JavaScript)

const fs = require("fs");
const path = require("path");
const text = fs.readFileSync(path.join(__dirname) + "/input.txt", "utf8");
let output = text
.split("\n")
.map(d => calcFuel(d))
.reduce((acc, curr) => acc + curr, 0);
console.log(output);

function calcFuel(mass) {
let fuel = calcFuelPerModule(mass);
if (fuel > 0) {
let fuelFuel = calcFuel(fuel);
if (fuelFuel > 0) {
fuel += calcFuel(fuel);
}
}
return fuel;
}

function calcFuelPerModule(mass) {
return Math.floor(+mass / 3) - 2;
}


Still works well! As long as it gets you the answer, it's good! :)

I saw someone use a ternary operator, and was super impressed. Might refactor mine later today to test that. :) Didn't even think of it!
