User reduce function to create an Object from an array.

const array = [
  { id: "198", included: true },
  { id: "199", included: true },
  { id: "202", included: false },
];

const result = array.reduce((acc, curr) => {
  acc[curr.id] = curr.included;

If you want get newObj from array like your body question. Try this with reduce is shorten

const array = [
          { id: '198', included: true },
          { id: '199', included: true },
          { id: '202', included: false },
        ];
    const newObj = array.reduce((prev, curr) => ({...prev, [curr.id]: curr.included}),{})
    console.log(newObj)
