I have a table in my react app and it gets its data from API.

I want to sort one of its columns. `a[obj1][obj2]` or `b[obj1][obj2]` Usually is a string of numbers and sometimes are equal to `"-"` `(Dash)`
this is my sort function:

```
if (order === "DEF") {
  const sorted = props.currency.sort((a, b) =>
    Number(a[obj1][obj2]) > Number(b[obj1][obj2])
      ? 1
      : Number(b[obj1][obj2]) > Number(a[obj1][obj2]) || a[obj1][obj2] === "-"
      ? -1
      : 0
  );
  props.setCurrency(sorted);
  setOrder("ASC");
} else if (order === "ASC") {
  const sorted = props.currency.sort((a, b) =>
    Number(a[obj1][obj2]) < Number(b[obj1][obj2]) || a[obj1][obj2] === "-"
      ? 1
      : Number(b[obj1][obj2]) < Number(a[obj1][obj2])
      ? -1
      : 0
  );
  props.setCurrency(sorted);
  setOrder("DSC");
} else {
  const sorted = defaultCurrency;
  props.setCurrency(sorted);
  setOrder("DEF");
}

```

After the sort is called I want to behave with `"-"` like a zero,
but the items which are equal to `"-"`are always placed on the top of the table when the order is equal to **ASC** or **DSC**, while the other items of the array are sorted correctly.
