Clean Code Principles

Write code that humans can understand. Code is read far more often than it's written.

Naming

Variables

// BAD
const d = 86400000; // what is this?
const yyyymmdd = formatDate(date);
const list = getUsers();

// GOOD
const MILLISECONDS_PER_DAY = 86400000;
const formattedDate = formatDate(date);
const users = getUsers();
