Or for...of

const arr = [
  {key: "A", value: {count:2}},
  {key: "B", value: {count:5}},
  {key: "C", value: {count:1}}
];
for (let v of arr) v.value = v.value.count;
console.log(arr);

Though unlike map() this will mutate arr;

Use map for this.

let arr = [
  {key: "A", value: {count:2}},
  {key: "B", value: {count:5}},
  {key: "C", value: {count:1}}
];

let result = arr.map(obj => { return { key: obj.key, value: obj.value.count }});
console.log(result);

You could use map

const data = [
  { key: "A", value: { count: 2 } },
  { key: "B", value: { count: 5 } },
  { key: "C", value: { count: 1 } },
]

const res = data.map((obj) => ({
  key: obj.key,
  value: obj.value.count,
}))

console.log(res)
