How to perform for loop inside backticks in javascript?

Question

I have group by an array of elements based on their resturant id.

function grouparray(list,key)
   {
       return list.reduce(function(rv,x){
           (rv[x[key]] = rv[x[key]] || []).push(x);
           return rv;
       },{});
   };
   var group = grouparray(cartArray,"resturantid");

it gives an output like

{1: Array(3), 2: Array(3)}

It is array inside an array.

now i want to loop this inside backticks Full Code:

function displaycheckout()
{
    var cartArray = shoppingCart.listCart();

   function grouparray(list,key)
   {
       return list.reduce(function(rv,x){
           (rv[x[key]] = rv[x[key]] || []).push(x);
           return rv;
       },{});
   };
   var group = grouparray(cartArray,"resturantid");

    for(i in group)
    {

         output +=
         ` Resturant Name : ${group[i][0].resturant}
         `
         for(a in group[i]){
          `
            menu ${group[i][a].food}
          `
      }
}

But it doesn't work

@Tushar group[ i ] is the main loop inside that loop there is resturant menus. — ram ram, Jul 05 '20 at 06:47
This seems like an [XY problem](https://meta.stackexchange.com/questions/66377). Please post the input and the expected output? — adiga, Jul 05 '20 at 07:23

You can use Array#map on Object.values.

output +=
         ` Resturant Name : ${group[i][0]}
          ${Object.values(group[i]).map(({food})=>"Menu " + food).join("\n")}
         `
