How To Flatten Out The Array And Assign New Keys? (ts, Js)

From this long JSON file, I want to pick few keys and values. [{ c_id: '1', c: 'google', displayName: 'display name', myResults: [{ //type: Array type:

Solution 1:

const result = data.flatMap(({ c_id, c, index, myResults }) => ([
    { id: c_id, label: c, index }, 
    ...myResults.map(({ id, label }) => ({ id, label }))
  ]))

Maybe this would work, but I'm just guessing because your data seems inconsistent. c_id and id seem to get switched, google is the "c" key but facebook is the "connector key"
