replacing the key value with another property in array of objects

merging array with object and returning an array with all the properties with array of object value or null 

let object = {
  keys: {
    test1: {label: "Test_1"},
    test2: {label: "Test_2"},
    test3: {label: "Test_3"}
  }
}

let data = [{test1: "1", test2: "2", default:"123134" }, {test1: "1", test2: "2", default:"123134"}, {test1: "1", test3: "3"}, {test3: "3"}]

I am expecting the below array of objects

let expectedArray = [{Test_1: "1", Test_2: "2", Test_3: null ,default:"123134" }, {Test_1: "1", Test_2: "2", Test_3: null,  default:"123134"}, {Test_1: "1", Test_3: "3", Test_2:null }, {Test_3: "3", Test_1: null, Test_2: null}]

Tried below snippet

let res = data.map(o => {
  let obj = {}
  let c = Object.keys(o).forEach(aa => {
      obj[object.keys[aa].label] = o[aa]
  })
  return obj
})

Any help appreciated

You could replace existent key of object and rebuild new objects.

var object = { keys: { test1: { label: "Test 1" }, test2: { label: "Test 2" }, test3: { label: "Test 3" } } },
    data = [{ test1: "1", test2: "2", default: "123134" }, { test1: "1", test2: "2", default: "123134" }, { test1: "1", test3: "3" }, { test3: "3" }],
    templates = Object.values(object.keys).map(({ label }) => ({ [label]: null })),
    result = data.map(o => Object.assign(
        {},
        ...templates,
        ...Object
            .entries(o)
            .map(([k, v]) => ({ [k in object.keys ? object.keys[k].label : k]: v }))
    ));

console.log(result);
.as-console-wrapper { max-height: 100% !important; top: 0; }
