JavaScript Clean Code 🛠

Use getters and setters 💡

Bad :

function makeBankAccount() {

  return {
    balance: 0,
    // ...
  };
}

const account = makeBankAccount();
account.balance = 100;

Good :

function makeBankAccount() {
  let balance = 0;

  function getBalance() {
    return balance;
  }

  function setBalance(amount) {
    balance = amount;
  }

  return {
    getBalance,
    setBalance,
  };
}

const account = makeBankAccount();
account.setBalance(100);

Async/Await are even cleaner than Promises 💡

Bad :

get('https://en.wikipedia.org/wiki/Robert_Cecil_Martin')
  .then((response) => {
    return writeFile('article.html', response);
  })
  .then(() => {
    console.log('File written');
  })
  .catch((err) => {
    console.error(err);
  });

Good :

async function getCleanCodeArticle() {
  try {
    const response = await get('https://en.wikipedia.org/wiki/Robert_Cecil_Martin');

    await writeFile('article.html', response);

    console.log('File written');
  } catch(err) {
    console.error(err);
  }
}
