unicorn/switch-case-break-position Style

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

What it does

Enforce consistent break/return/continue/throw position in case clauses.

Why is this bad?

Enforce that terminating statements (break, return, continue, throw) appear inside the block statement of a case clause, not after it. This can happen when refactoring — for example, removing an if wrapper but leaving the break outside the braces.

Examples

Examples of incorrect code for this rule:

switch (foo) {
  case 1:
    {
      doStuff();
    }
    break;
}

Examples of correct code for this rule:

switch (foo) {
  case 1: {
    doStuff();
    break;
  }
}
