You can use reduce() method to create recursive function for this.

const data = {"name":"johny","lname":"walker","a_score":30,"b_score":40,"result":{"c_score":50,"d_score":60}}

const pick = (obj, key) => {
  return Object.keys(obj).reduce((r, e) => {
    if (typeof obj[e] == 'object') Object.assign(r, pick(obj[e], key))
    if (e.includes(key)) r[e] = obj[e]
    return r;
  }, {})
}

console.log(pick(data, '_score'))
