Merge objects in arrays

I have two arrays:

[{Name: "Jack", Depot: "5"}, {Name: "Jill", Depot: "6"}]

and

[{Depot Name: "Edgware"}, {Depot Name: "Romford"}]

I need to take the objects from the second array and merge them with the objects in the first array to produce a result of:

[{Name: "Jack", Depot: "5", Depot Name: "Edgware"}, {Name: "Jill", Depot: "6", Depot Name: "Romford"}]

Any help with this would be much appreciated

var array1 = [{
  Name: "Jack",
  Depot: "5"
}, {
  Name: "Jill",
  Depot: "6"
}];
var array2 = [{
  'Depot Name': "Edgware"
}, {
  'Depot Name': "Romford"
}];

for (var a in array1) {
  for (var p in array1[a]) {
    //to esclude all possible internal properties
    if (array1[a].hasOwnProperty(p)) {
	 array2[a][p] = array1[a][p];
    }
  }
}

console.log(array2);

Here is a solution with Object.assign().

P.S: Check for browser compatibility, this solution might not work in IE

var arr1 = [{
  "Name": "Jack",
  "Depot": "5"
}, {
  "Name": "Jill",
  "Depot": "6"
}];

var arr2 = [{
  "Depot Name": "Edgware"
}, {
  "Depot Name": "Romford"
}];

var arr1Copy = arr1;
var newArr = arr1Copy.map(function(v, i) {
  return Object.assign(v, arr2[i]);
});

console.log(newArr);
