Generate multi dimensional array with key value in javascript

Question

I have an array from json like this:

{"1001":"Account1","1002":"Account2","1003":"Account3"}

and i need convert it to key value format:

[{id:"1001",name:"Account1"},
{id:"1002",name:"Account2"},
{id:"1003",name:"Account3"}]

To do this i wrote this function:

function arrayToMultiArray(list) {
    var matrix = [], i;
    i = -1;
    for (var key in list) {
        i++;
        matrix[i] = [];
        matrix[i].push({"id":key, "name":list[key]});
    }
    return matrix;
}

but the generated array has brackets for each array

[[{id:"1001",name:"Account1"}],
[{id:"1002",name:"Account2"}],
[{id:"1003",name:"Account3"}]]

How can i remove brackets of internal arrays?

You added array in array.

Just change

i++;
matrix[i] = [];
matrix[i].push({"id":key, "name":list[key]});

to

matrix.push({"id":key, "name":list[key]});

you are creating a multidimensional array.

remove this

 i++;
 matrix[i] = [];

and do this directly

matrix.push({"id":key, "name":list[key]});

You could do the same with Object.keys and Array.prototype.map

var obj = {"1001":"Account1","1002":"Account2","1003":"Account3"};
var arr = Object.keys(obj).map(function(key) {
  return { id : key, name : obj[key] }
});

console.log(arr);
