unicorn/no-useless-switch-case Pedantic

🚧 An auto-fix is planned for this rule, but not implemented at this time.

Disallows useless default cases in switch statements.

An empty case before the last default case is useless, as the default case will catch it regardless.

Examples of incorrect code for this rule:

javascript

switch (foo) {
  case 1:
  default:
    handleDefaultCase();
    break;
}

Examples of correct code for this rule:

javascript

switch (foo) {
  case 1:
  case 2:
    handleCase1And2();
    break;
}
