How to push all objects into another array using AngularJs

Question

I have 2 arrays,

$scope.first = [
  { fName:'Alex', lName='Doe' },
  { fName:'John', lName='S' }
]

var second= [
  { fName:'Tom', lName='M', email:'[email protected]' },
  { fName:'Jerry', lName='L', email:'[email protected]' }
]

I need to push second array into first array and want to result like:

$scope.first = [
  { fName:'Alex', lName='Doe' },
  { fName:'John', lName='S' },
  { fName:'Tom', lName='M', email:'[email protected]' },
  { fName:'Jerry', lName='L', email:'[email protected]' }
]

with concat...?

If you want to push elements from one array into an existing array you can do

[].push.apply($scope.first, second);

If you want to create a new array that contains elements of both arrays, use concat:

$scope.first = $scope.first.concat(second);

[].push.apply() what you mean by [ ], first array($scope.first)?

[] is an array :) You could also write Array.prototype.push.apply(...) or $scope.first.push.apply(...) or second.push.apply(...). It doesn't matter. It#s just a way to reference the push method.

[] in js represents an array. Read more here - stackoverflow.com/questions/33514915/…

I would try $scope.first.concat($scope.second)

$scope.first = [
  { fName:'Alex', lName='Doe' },
  { fName:'John', lName='S' }
]

var second= [
  { fName:'Tom', lName='M', email:'[email protected]' },
  { fName:'Jerry', lName='L', email:'[email protected]' }
]

$scope.first = $scope.first.concat(second)
