Javascript switch case - default parameter causing error

I have some code that defines behavior based on which input the code is processing at that moment. The code looks something like this:

switch(inputOption.name) {
 case 'NAME_1':
  switch(inputOption.type.toLowerCase()) {
    case 'radio':
      //some code
    case 'text':
      //some code
    ...
    case 'image':
      //some code

    default:
      return inputOption.value;
      break;
   }
  break;

  default:
    break;
 }

Some cascading cases are also included in the code. The default parameter raises an error. The error is listed as

    the default case is already defined

What is causing this error? The error shows up in the package folder, but the file shows no errors in the package view, but it shows errors when opening the file. I assumed it had something to do with the second default declaration, but was unable to remove it.

You will miss the break statement for your "NAME_1" outer case 



switch(inputOption.name) {
 case 'NAME_1':
  switch(inputOption.type.toLowerCase()) {
    case 'radio':
      //some code
    case 'text':
      //some code
    ...
    case 'image':
      //some code

    default:
      return inputOption.value;
      break;
   }
   break; // <-------------------------------------------------- ADD THIS

  default:
    break;
 }
