Using the same if else statement with two variables

I have the following if statement:

let panoX = 0
if (pano.x === 0) {
  panoX = 0
} else if (pano.x === null) {
  panoX = 200
} else {
  panoX = pano.x
}

// This will be sent in a form
{
  x: panoX,
  y: panoY
}

It sets panoX based on the value of pano.x. But I also have a pano.y, that goes through the same if statement. How can I deal with pano.y without having to write a new if statement?

(Note: I can't do x: pano.x || 200 because 0 is falsy in JavaScript. So setting pano.x to 0 makes x: be 200.

function panoFix(x){
   if (x === 0) return 0;
   if (x === null) return 200;
   return x;
}

// This will be sent in a form
{
  x: panoFix(pano.x),
  y: panoFix(pano.y)
}

The first condition seems to be redundant (same as the fallback case), so it could be shortened to

function panoFix(x) { return x === null ? 200 : x }

in JS:

var panoX = 200, panoY = 200;
if(pano !== null){
  panoX = pano.x;
  panoY = pano.y;
}
