Python:

match subject:
    case pattern1:
        # Code to execute if subject matches pattern1
        pass
    case pattern2:
        # Code to execute if subject matches pattern2
        pass
    case _:
        # Code to execute if no other pattern matches (the default case)
        pass

So yes, Python will fold on case statements.

JavaScript:

switch (expression) {
  case value1:
    // Code to be executed if expression === value1
    break;
  case value2:
    // Code to be executed if expression === value2
    break;
  // ... more case clauses
  default:
    // Code to be executed if no case matches
}

… doesn’t fold on case

… BUT, that’s because it folds on BLOCKS, not STATEMENTS:

switch (expression) {
  case value1:
  {
    // Code to be executed if expression === value1
    break;
  }
  case value2:
  {
    // Code to be executed if expression === value2
    break;
  }
  // ... more case clauses
  default:
  {
    // Code to be executed if no case matches
  }
}
