描述

If the body of if contains one of these keywords, the else is moot:

  • throw
  • break
  • continue
  • return

This slightly overlaps with https://eslint.org/docs/rules/no-else-return

This was inspired by https://github.com/eslint/eslint/issues/13067.

This could be auto-fixed, but we should take care to properly move any comments.

Fail

if (foo) {
	throw new Error();
} else {
	console.log('🦄');
}

Pass

if (foo) {
	throw new Error();
} 

console.log('🦄');
