I've tried a map and forEach loop and still can't get this to sort by alphabetical order. Not sure what I am missing here.

My array:

```
const filtData = [
  [
    {
      gameType: "Rowing",
    },
    {
      gameType: "Rowing",
    },
    {
      gameType: "Rowing",
    },
  ],
  [
    {
      gameType: "Golf",
    },
    {
      gameType: "Golf",
    },
    {
      gameType: "Golf",
    },
  ],
  [
    {
      gameType: "Soccer",
    },
    {
      gameType: "Soccer",
    },
    {
      gameType: "Soccer",
    },
  ],
  [
    {
      gameType: "Baseball",
    },
    {
      gameType: "Baseball",
    },
    {
      gameType: "Baseball",
    },
  ],
]

```

Js:

```
filtData.forEach(d => d.sort((a,b) => a.gameType - b.gameType))
console.log(filtData) /* <--fails  */

const sortedData = filtData.map((d) => d.sort((a, b) => {
  return a.gameType - b.gameType;
}));
console.log("sortedData", sortedData)/* <--fails  */

```
