How get values and key in the object array JSON

Question

I have a JSON below :

{
  "sports": [
    { "id": 1, "name": "Soccer" },
    { "id": 2, "name": "Basketball" }
  ]
}

How I can read the id and the name in typeScript ? Currently I use

let result = this.dataService.getJSON()

public getJSON(): Observable<any> {
  return this.http.get('./assets/json/data.json');
}

But I have a error message

map is not a function

I don't know How I can parse the JSON,

I would like have this result.

[
  { "id": 1, "name": "Soccer" },
  { "id": 2, "name": "Basketball" }
]

Thank for your help.

There is no use of `map` in your code. Note that `result` is an `Observable`, which I don't believe has a `map` function... — Heretic Monkey, Jun 18 '20 at 14:41

If you are using Observables, you need to subscribe for thread to receive a response:

this.dataService.getJSON().subscribe(data => {
  console.log(data);
});
