What is the best method for accessing a specific key value in a JSON file?

I am looking to extract a specific field data from a JSON list

Here is the example JSON data:

{
"data": [
    {"answer": "Yes","email": "aaaa.cpm","color": "Maroon"},
    {"answer": "No","email": "bbbb.cpm","color": "White"},
    {"answer": "Yes","email": "cccc.cpm","color": "Black"}
]}

In my service file

 getCarsSmall() {
    return this.http.get<any>('assets/data/cars-large.json').suscribe(d=>{
console.log(d)
})     
  }

The desired output should look like this

Output

 [{"email": "aaaa.cpm","color": "Maroon"},{"email": "bbbb.cpm","color": "White"},{"email": "cccc.cpm","color": "Black"}]

If all you need is email data, you can easily retrieve it by using:

console.log(d["data"][0]['email'])

This will allow you to access the first email in the dataset.

Furthermore, if you need to access each email individually, you can use iterators or loops like this:

for (var _i = 0; _i < d["data"].length; _i++) {
   console.log(d["data"][_i]['email'])
}
