Disallow classes that only have static members

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

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

A class with only static members could just be an object instead.

// ❌
class X {
	static foo = false;
	static bar() {};

const X = {
	foo: false,
	bar() {},
};

class X {
	static foo = false;
	static bar() {}

	constructor() {}
}

// ✅
class X {
	static foo = false;
	static bar() {}

	unicorn() {}
}

class X {
	static #foo = false;
	static bar() {}
