I have an array of objects like so

```
[
   {
      "id":1,
      "name":"Competition One",
      "entrants": [
          {
              "id":1,
              "competitionId":1,
              "duration":"3 minutes",
           },
           {
              "id":2,
              "competitionId":1,
              "duration":"2 hours",
           },
      ]
   },
   {
      "id":2,
      "name":"Competition Two",
      "entrants": [
            {
              "id":3,
              "competitionId":2,
              "duration":"5 hours",
           },
      ]
   },
]

```

What I am trying to do is get a flat array containing only the entrants, as such I am doing this

```
const entrants = competitions.flatMap((comp) => {
    return comp.entrants;
});

```

This seems to do the job. I now have the following

```
[
   {
      "id":1,
      "competitionId":1,
      "duration":"3 minutes",
   },
   {
      "id":2,
      "competitionId":1,
      "duration":"2 hours",
   },
   {
      "id":3,
      "competitionId":2,
      "duration":"5 hours",
   }
]

```

However, what I can't figure out is how to add a new field within the above data that contains the name of the competition. So what I am after is this

```
[
   {
      "id":1,
      "competitionId":1,
      "name": "Competition One"
      "duration":"3 minutes",
   },
   {
      "id":2,
      "competitionId":1,
      "name": "Competition One"
      "duration":"2 hours",
   },
   {
      "id":3,
      "competitionId":2,
      "name": "Competition Two"
      "duration":"5 hours",
   }
]

```

How can this be achieved? I know how to do this with conventional loops, but trying to force myself to learn the ES6 way of doing things. Is this where a reduce could come in handy?

Any advice appreciated.

Thanks
