HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];

Tests:

merge lodash
const merged = _(arr1) // start sequence .keyBy('member') // create a dictionary of the 1st array .merge(_.keyBy(arr2, 'member')) // create a dictionary of the 2nd array, and merge it to the 1st .values();
merge find
const merged = arr1.filter( element1 => ! arr2.find( element2 => element1[props] === element2[props]) ).concat(arr2);
merge some
const merged = arr1.filter( element1 => ! arr2.find( element2 => element1[props] === element2[props]) ).concat(arr2);
