Update an array of objects by incorporating additional properties from another array, even if the two arrays are of different lengths. When the iteration of the array is complete, it should

Is there a way to merge two arrays of objects with different keys? I want to combine the keys of the second array with those of the first one. How can I accomplish this task?

  $scope.links = [
    {
      name: 'JRD',
      status: 'active'
    },
    {
      name: 'JRM',
      status: 'active'
    },
    {
      name: 'JRH',
      status: 'active'
    }
  ];

  $scope.colors = [
        {
            color: 'red',
            value: '#f00'
        },
        {
            color: 'green',
            value: '#0f0'
        },
        {
            color: 'blue',
            value: '#00f'
        },
        {
            color: 'cyan',
            value: '#0ff'
        },
        {
            color: 'magenta',
            value: '#f0f'
        },
        {
            color: 'yellow',
            value: '#ff0'
        },
    ];

I aim to merge these two arrays to create a new merged array shown below.

[
    {
      name: 'JRD',
      status: 'active',
      color: 'red',
      value: '#f00'
    },
    {
      name: 'JRM',
      status: 'active',
      color: 'green',
      value: '#0f0'
    },
    {
      name: 'JRH',
      status: 'active',
      color: 'blue',
      value: '#00f'
    }
  ];

Are there any methods like reduce or forEach that can help achieve this? Any assistance on this matter would be highly appreciated.

Answer №1

To transform the elements in $scope.links into a new array, you can apply the modulo operator % to ensure they remain within the boundaries of $scope.colors. Merge the objects using Object.assign after obtaining them, as shown below:

var merged = $scope.links.map(function(link, index) {
    return Object.assign({}, link, $scope.colors[index % $scope.colors.length]);
});

Answer №2

Is it possible to iterate through both arrays simultaneously?

$scope.combined = [];
for(var y = 0; y < $scope.links.length && y < $scope.colors.length; y++){
    $scope.combined.push(Object.assign({}, $scope.links[y], $scope.colors[y]));
}
