Short script to assist with ranking a list of items

ranking.js

const fs = require("fs");

const items = [
  // List of items
];

function prompt(input) {
	const b = Buffer.alloc(1024);
	console.log(input);
	fs.readSync(fs.openSync("/dev/tty"), b);
	return b.toString()[0];
}

const getRandomItem = () => items[Math.floor(Math.random() * items.length)];

const db = Object.fromEntries(items.map(item => [item, 0]));

const limit = 50;

for(i = 0; i < limit; i++) {
	const i1 = getRandomItem();
	let i2 = undefined;
	while(!i2) {
		i2 = getRandomItem();
		if(i2 === i1) i2 = undefined;
	}
	const res = prompt(`${i1} vs ${i2}`);
	db[res === "1" ? i1 : i2]++;
}

console.log(db);
