Prinsip Clean Code kanggo Developer JavaScript

Kode sing resik mbantu perawatan lan kerja bareng. Iki prinsip sing becik dingerteni saben developer JavaScript.

Jeneng sing Cetha

Gunakake jeneng sing nerangake tujuane:

// Bad
const d = new Date();

// Good
const currentDate = new Date();

Fungsi

Gawe fungsi sing cilik lan fokus:

• Garap siji bab kanthi apik.
• Watesi jumlah parameter fungsi, saapike 0–3.
• Gunakake jeneng sing cetha.

DRY (Don't Repeat Yourself)

Pindhahake pola sing bola-bali dadi fungsi sing bisa dienggo maneh:

// Instead of repeating validation
function validateEmail(email) {
  const regex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  return regex.test(email);
}

function validatePhone(phone) {
  const regex = /^\d{10,}$/;
  return regex.test(phone);
}

Komentar

Gunakake komentar kanggo nerangake ngapa, dudu apa. Kode sing apik kudune wis cukup cetha.

Nangani Kesalahan

Tansah tangani kesalahan kanthi becik:

try {
  await riskyOperation();
} catch (error) {
  logger.error(error);
  throw new CustomError('Operation failed');
}

Kesimpulan

Nulis clean code kuwi skill sing mundhak yen dilatih. Gunakake prinsip iki kanthi konsisten supaya kode luwih gampang dirumat.
