Hi
I have this array:

[
   {
      "role":{
         "code":"LA",
         "name":"Local administrator",
         "id":1
      }
   },
   {
      "role":{
         "code":"SA",
         "name":"System administrator",
         "id":2
      }
   }
]

and also the scopes array

"scopes":[
         {
            "type":{
               "id":1,
               "code":"COR",
               "name":"Description 1"
            },
            "ids":[
               1,
               2,
               3
            ],
            "cascade":false
         }
      ],"scopes":[
         {
            "type":{
               "id":2,
               "code":"TES",
               "name":"Test"
            },
            "ids":[
               55
            ],
            "cascade":true
         },
         {
            "type":{
               "id":1,
               "code":"COR",
               "name":"Description 1"
            },
            "ids":[
               77,
               88
            ],
            "cascade":true
         }
      ]

and an array of the the RoleId:

"roleId":1, "roleId":2

How can I combine all those to end up to the following JSON structure?

[
   {
      "role":{
         "code":"LA",
         "name":"Local administrator",
         "id":1
      },
      "scopes":[
         {
            "type":{
               "id":1,
               "code":"COR",
               "name":"Description 1"
            },
            "ids":[
               1,
               2,
               3
            ],
            "cascade":false
         }
      ],
      "roleId":1
   },
   {
      "role":{
         "code":"SA",
         "name":"System administrator",
         "id":2
      },
      "scopes":[
         {
            "type":{
               "id":2,
               "code":"TES",
               "name":"Test"
            },
            "ids":[
               55
            ],
            "cascade":true
         },
         {
            "type":{
               "id":1,
               "code":"COR",
               "name":"Description 1"
            },
            "ids":[
               77,
               88
            ],
            "cascade":true
         }
      ],
      "roleId":2
   }
]

Hello !

array.push(element) add 'element' at end of the array.

you search to combine your datas at the good place in the array.

it require to fetch the array, and to add datas at the good place.

JSON datas are strings first, but behave like n-dimensions array, you got root / and so sub levels themselves containing others sub levels of datas.

n-dimensionals arrays are {//root. {sub.. {subsub... }},{sub.. }, {sub.. {subsub... }} }
JSON is multi-datas type , there are all types of datas in ( strings , integers , objects ), sometimes functions too for scripting execution.

It's reading a 'hierarchy' because the root contains all elements.
each elements contains datas to read.

you can use 'index' with i++ to fetch the root , then reach a sub depth with a second loop, or a JSON parser/reader.
