  const arr =  [
        {
            "item_name": "Cake",
            "quantity": 1,
        },
        {
            "item_name": "Choclate",
            "out_of_stock_detail": {
                "out_of_stock_quantity": 1
            },
            "quantity": 3,
    
        }
    ]

let output = arr.sort((a,b) => {
   if(a.out_of_stock_detail){
    return 1 
  }else{
    return -1
  }
})

console.log(output)
