I got distracted during writing some code for a talk slide

nerd-snipe.js

const state = { test: 3, hello: 399, testinghhhh: 1 };

const stateWords = Object.keys(state);
const stateNumbers = Object.values(state);

const itemStr = 'Item';
const countStr = 'Count';

let longestWord = itemStr.length;
let longestNumber = countStr.length;

for (let word of stateWords) {
  // Add one for the ` ` after the entry
  longestWord = longestWord < word.length ? word.length : longestWord;
}

for (let number of stateNumbers) {
  const numStr = `${number}`;
  longestNumber = longestNumber < numStr.length ? numStr.length : longestNumber;
}


const getSpacing = (str, char, max) => {
  const addedLength = max - str.length;
  return char.repeat(addedLength);
}

const headerStr1 = `${itemStr}${getSpacing(itemStr, ' ', longestWord)}`;
const headerStr2 = `${countStr}${getSpacing(countStr, ' ', longestNumber)}`;
const headerStr = `${headerStr1} | ${headerStr2}`;
// Plus three because of the two spaces plus the `|`
const totalLength = headerStr.length;
const seperatorStr = getSpacing('', '-', totalLength);
const initialHeader = `${headerStr}\n${seperatorStr}\n`; 

const tableString = stateWords.reduce((stateStr, word) => {
  const numberOfInstances = `${state[word]}`;
  const addedSpaceWord = getSpacing(word, ' ', longestWord);
  const addedSpaceNumber = getSpacing(numberOfInstances, ' ', longestNumber);
  return `${stateStr}${word}${addedSpaceWord} | ${addedSpaceNumber}${numberOfInstances}\n`;
}, initialHeader);

console.log('\n', tableString);

/** Should turn into:
