How to transform an Object into Json on Ionic?

Question

I have the following object. How to turn this object into a Json?

 initializeItems() {
   this.items = [
 {id: '1', nome:'Abaéte', rua:'Moacir', cidade:'Capão da Canoa', bairro:'Centro', numero:'396', ano:'1964', aptos:'55', adm:'Adsel', zelador:'Hugo', contato1:'(51) 0 0000 - 0000', contato2: '(51) 0000 - 0000', imagem:'assets/img/Abaete-min.jpg'},
];

And I want to turn it into Json

{
"predios" : {
    "adm" : "Adsel",
    "ano" : 1964,
    "aptos" : 55,
    "bairro" : "Centro",
    "cidade" : "Capão da Canoa",
    "contato1" : "(51) 9 0000 - 0000",
    "contato2" : "(51) 0000 - 0000",
    "id" : 1,
    "imagem" : "Abaete-min.JPG",
    "nome" : "Abaéte",
    "numero" : 396,
    "rua" : "Moacir",
    "zelador" : "Hugo"
  }
}

you can use

JSON.stringify()

function initialize() {
var items = [{id: '1', nome:'Abaéte', rua:'Moacir', cidade:'Capão da Canoa', bairro:'Centro', numero:'396', ano:'1964', aptos:'55', adm:'Adsel', zelador:'Hugo', contato1:'(51) 0 0000 - 0000', contato2: '(51) 0000 - 0000', imagem:'assets/img/Abaete-min.jpg'}];

var jsonObject = {"predios": items[0]}

console.log(JSON.stringify(jsonObject));
} 
initialize();

To achieve that,

Get the first element of this.items as it is an array
Assign the first element within an object

var prediosJsonObj = {"predios": this.items[0]}

To clear up any confusion, JSON supports 2 types of data structure:

Collection of name/value pairs (Object, dictionary, etc)
Ordered list of values (Array, list, etc)

this.items is already considered JSON with an array structure. What you wanted is how to transform JSON array to a JSON object.
