no-zero-fractions

📝 Disallow number literals with zero fractions or dangling dots.

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

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

There is no difference in JavaScript between, for example, 1, 1.0 and 1., so prefer the former for consistency and brevity.
