prefer-date-now

📝 Prefer Date.now() to get the number of milliseconds since the Unix Epoch.

💼 This rule is enabled in the following configs: ✅ recommended, ☑️ unopinionated.

🔧 This rule is automatically fixable by the --fix CLI option.

Date.now() is shorter and nicer than new Date().getTime(), and avoids unnecessary instantiation of Date objects.

// ❌
const foo = Number(new Date());
