Answer 1

var arr = [
    {
      "fdId": "1ech3enh02snwcw1q9fd0q2jv026k1hb",
      "actionType": "agree",
      "triggerTime": 48,
    },
    {
      "fdId": "1ecp2el9j35ow2dw34t42dd1klcdea1s",
      "actionType": "forward",
      "triggerTime": 27,
    }
];
var newArr = [];

arr.forEach(({ fdId, ...rest }) => newArr.push({ id: fdId, ...rest }));
