Require new when throwing an error

✅ This rule is enabled in the recommended config.

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

While it's possible to create a new error without using the new keyword, it's better to be explicit.

Fail

throw Error();

throw TypeError('unicorn');

throw lib.TypeError();

Pass

throw new Error();

throw new TypeError('unicorn');

throw new lib.TypeError();
