javascript - 如何通过键过滤数组并使用javascript将值推送到另一个数组

Question

这是我的第一个数组

data=  [{
  "id":1111,
  "date":"2020-08-03T08:00:00+00:00",
  "age":23,
   "email":"test@yahoo.com",
   "address":"phill road",
   "salary":1222.00
},

 {
  "id":222,
  "date":"2020-08-03T08:00:00+00:00",
  "age":24,
   "email":"tes22t@yahoo.com",
   "address":"phill2222 road",
   "salary":3344
}
]

第二个数组应如下所示

  dataNew=  [1222.00,3344]

我需要第二个只包含 的数组工资值 .如何过滤第一个数组，如果 键名 = "salary"，将值推送到新数组。搜索了很多建议，但似乎没有任何对我有用..

   "address":"phill road",
   "salary":1222.00

 {
  "id":222,
  "date":"2020-08-03T08:00:00+00:00",
  "age":24,
   "email":"tes22t@yahoo.com",
   "address":"phill2222 road",
   "salary":3344
},
 {
  "id":223,
  "date":"2020-08-03T08:00:00+00:00",
  "age":24,
   "email":"tes22t@yahoo.com",
   "address":"phill2222 road"
}
]

console.log(data.filter(e => e.salary).map(e => e.salary));
