i have following two array objects 

```
27A: {id: 228, swift_code: "27", field_description: "Sequence of Total", 
line_description: "1/1 (Number)(Total)", commercial: false}

31B: {id: 230, swift_code: "31C", field_description: "Date of Issue", 
line_description: "dd/mm/yyyy", commercial: false}

31C: {id: 242, swift_code: "31D", field_description: "Expiry Date/Place 
(dd/mm/yyyy)", line_description: "IN SINGAPORE", commercial: true}

```

my second array 

```
67: {id: 228, swift_code: "27", field_description: "Sequence of Total", 
line_description: "1/1 (Number)(Total)", commercial: false}

44: {id: 230, swift_code: "31C", field_description: "Date of Issue", 
line_description: "dd/mm/yyyy", commercial: false}

12: {id: 242, swift_code: "31D", field_description: "Expiry Date/Place 
(dd/mm/yyyy)", line_description: "IN SINGAPORE", commercial: true}

```

i want to combined these two array together like bellow without modifying the order which means first array come first second array second 

like bellow

```
27A: {id: 228, swift_code: "27", field_description: "Sequence of Total", 
line_description: "1/1 (Number)(Total)", commercial: false}

31B: {id: 230, swift_code: "31C", field_description: "Date of Issue", 
line_description: "dd/mm/yyyy", commercial: false}

31C: {id: 242, swift_code: "31D", field_description: "Expiry Date/Place 
(dd/mm/yyyy)", line_description: "IN SINGAPORE", commercial: true}

67: {id: 228, swift_code: "27", field_description: "Sequence of Total", 
line_description: "1/1 (Number)(Total)", commercial: false}

44: {id: 230, swift_code: "31C", field_description: "Date of Issue", 
line_description: "dd/mm/yyyy", commercial: false}

12: {id: 242, swift_code: "31D", field_description: "Expiry Date/Place 
(dd/mm/yyyy)", line_description: "IN SINGAPORE", commercial: true}

```

i have used merge and array copy but its modifying the order 

```
angular.merge(arraiobj1, arraiobj2); 

```
