JS Replace does not work as expected

I have the following JS that takes an array of strings that removes n/a from the start of the array and put a space after each comma, but I’m not finding that to happen. Any suggestions?

I just get ,foo,place,data

let safetyItems = elements.iu1p3y1i["0"].selected_item.room_amenities;

// Check if safetyItems is an array
if (Array.isArray(safetyItems)) {
// Process each string in the array
let modifiedArray = safetyItems.map((item) => item.replace(/n/a/g, “”).replace(/, /g, “\n”));
return modifiedArray;
} else {
return “error”;
}
