To me "else after return" is just incompetent gibberish. It's a pointless redundancy showing an utter and complete lack of understanding what "return" even does.

It's as mind-numbingly dumbass as:

if (a === 1 && b === 1) {
  // do something
} else if (a === 1 && b === 2) {
  // do something else
}

Do they not even teach basic code logic anymore?

I rank it on the “well no shit’ scale alongside such derpitude as:

} // end block

or trashy incompetent markup like:

<form role="form">
<button role="button" class="button">
