Conditional returns or single variable return

Question

I was wondering what if there's any preferable way of returning values conditionally. And if not, if it makes any different for minified Javascript.

I was checking Google Javascript Style guide and they don't name anything about the issue. Same with Airbnb guidelines

Using multiple conditional returns:

function demo(x, y) {
   if (x < y) {
       return getX();
   } else if (x === y) {
       return 'equal';
   }
   return getY();
}

Or having a single return with and making use of a variable:

function demo(x, y) {
    var position;

    if (x < y) {
        position = getX();
    } else if (x === y) {
       position = 'equal';
    } else {
        position = getY();
    }
    return position;
}

Answer 1

The following is a definition of the return statement.

The return statement stops the execution of a function and returns a value from that function.

Clearly, a conditional return would have to include a condition before that return. About preference, as the word implies, it is really is a matter of habits. If you're used to one syntax from, say, another language, or you just like it better - use it, as it will probably reduce syntax errors.

About minifying the code, I believe the switch/case syntax best works for simple conditions, and the ternary operation fits well for two-side conditions.

(Caution! philosophical paragraph ahead)

But again, in the end, the important thing, I believe, is that you will understand the code you write. And, with experience, you will find what suits you best.
