In my meteor app , this code

       var format = [];
       var formats = [];



        var length = result.formats.length - 1;
        for (var i = 0 ; i <= length; i++) {
          var type = result.formats[i].type;
          var type2 = type.split(/[;,]/);

              var typee = type2[0];
               var resolutions = result.formats[i].resolution;
               var urls = result.formats[i].url;


                format.push({
                  "Type": typee,
                  "resolution": resolutions
                  // "url": urls
                })


        };



        var formatt = JSON.stringify(format, null, 4);
        Session.set('format', JSON.stringify(format, null, 4));
        console.log(formatt);

give me this result

[
    {
        "Type": "video/webm",
        "resolution": "360p"
    },
    {
        "Type": "video/mp4",
        "resolution": "360p"
    },
    {
        "Type": "video/x-flv",
        "resolution": "240p"
    },
    {
        "Type": "video/3gpp",
        "resolution": "240p"
    },
    {
        "Type": "video/3gpp",
        "resolution": "144p"
    },
    {
        "Type": "video/mp4",
        "resolution": "360p"
    },
    {
        "Type": "video/webm",
        "resolution": "360p"
    },
    {
        "Type": "video/mp4",
        "resolution": "240p"
    },
    {
        "Type": "video/webm",
        "resolution": "240p"
    },
    {
        "Type": "video/mp4",
        "resolution": "144p"
    },
    {
        "Type": "video/webm",
        "resolution": "144p"
    },
    {
        "Type": "audio/webm",
        "resolution": null
    },
    {
        "Type": "audio/mp4",
        "resolution": null
    },
    {
        "Type": "audio/webm",
        "resolution": null
    },
    {
        "Type": "audio/webm",
        "resolution": null
    },
    {
        "Type": "audio/webm",
        "resolution": null
    } ]

How can I do to get only the values without parentheses; something like that

    "Type": "video/webm",
    "resolution": "360p"


    "Type": "video/mp4",
    "resolution": "360p"


    "Type": "video/x-flv",
    "resolution": "240p"


    "Type": "video/3gpp",
    "resolution": "240p"


    "Type": "video/3gpp",
    "resolution": "144p"


    "Type": "video/mp4",
    "resolution": "360p"


    "Type": "video/webm",
    "resolution": "360p"


    "Type": "video/mp4",
    "resolution": "240p"


    "Type": "video/webm",
    "resolution": "240p"


    "Type": "video/mp4",
    "resolution": "144p"


    "Type": "video/webm",
    "resolution": "144p"


    "Type": "audio/webm",
    "resolution": null


    "Type": "audio/mp4",
    "resolution": null


    "Type": "audio/webm",
    "resolution": null


    "Type": "audio/webm",
    "resolution": null


    "Type": "audio/webm",
    "resolution": null

I spent two days without solution :(

Thank's for you help

Edit: what I want to do is to retrieve an array of values or cursors used in {{#each}} in a template

     {#each format}} 
        <tr>

             {{> postItem}}


        </tr>
        {{/each}} 


<template name="postItem">

        {{Type}}
        {{resolution}} 
        {{url}}

</template>





Template.hello.helpers({


     format:function(){
     return Session.get('format');
    }

  });

This will work.

var arr = [{"Type":"video/webm","resolution":"360p"},{"Type":"video/mp4","resolution":"360p"},{"Type":"video/x-flv","resolution":"240p"},{"Type":"video/3gpp","resolution":"240p"},{"Type":"video/3gpp","resolution":"144p"},{"Type":"video/mp4","resolution":"360p"},{"Type":"video/webm","resolution":"360p"},{"Type":"video/mp4","resolution":"240p"},{"Type":"video/webm","resolution":"240p"},{"Type":"video/mp4","resolution":"144p"},{"Type":"video/webm","resolution":"144p"},{"Type":"audio/webm","resolution":null},{"Type":"audio/mp4","resolution":null},{"Type":"audio/webm","resolution":null},{"Type":"audio/webm","resolution":null},{"Type":"audio/webm","resolution":null}]

var output = arr.map(function(obj){
  return JSON.stringify(obj).replace(/{|}/g,'')
}).join('\r\n');

console.log(output);

will give below

"Type":"video/webm","resolution":"360p"
"Type":"video/mp4","resolution":"360p"
"Type":"video/x-flv","resolution":"240p"
"Type":"video/3gpp","resolution":"240p"
"Type":"video/3gpp","resolution":"144p"
"Type":"video/mp4","resolution":"360p"
"Type":"video/webm","resolution":"360p"
"Type":"video/mp4","resolution":"240p"
"Type":"video/webm","resolution":"240p"
"Type":"video/mp4","resolution":"144p"
"Type":"video/webm","resolution":"144p"
"Type":"audio/webm","resolution":null
"Type":"audio/mp4","resolution":null
"Type":"audio/webm","resolution":null
"Type":"audio/webm","resolution":null
"Type":"audio/webm","resolution":null
