formatting dynamic json array

I have an json array as follows:

Maindata=[
  {"name":"string1"},
  {"name":"string2"},
  {"name":"string3"}
 ];

what I need is an array of following type:

data=[
  {
   "name":"string1",
   "name":"string2",
   "name":"string3"
  }
 ];

can anybody help me with some methods to obtain required json from original array. (note: maindata is json array formed dynamically thats why its structure is like that)

Thanks in advance

You can use Array.forEach or Array.reduce to iterate though the items of the Maindata object and for each item you can iterate through its keys(using Object.keys) and group the data into a new structure.(See the below snippet)

Solution using Array.forEach

var Maindata=[
  {"name1":"string1"},
  {"name2":"string2"},
  {"name3":"string3"}
 ];
 var result = {};
 var newMaindata=[];
 Maindata.forEach(function(el){
 Object.keys(el).forEach(function(key){
 result[key]=el[key];
 });
 });
 newMaindata.push(result);
 
 console.log(newMaindata);

Solution using Array.reduce

var Maindata = [{
  "name1": "string1"
}, {
  "name2": "string2"
}, {
  "name3": "string3"
}];
var result ;
var newMaindata = [];
result = Maindata.reduce(function(acc,el) {
  Object.keys(el).forEach(function(key) {
    acc[key] = el[key];
  });
  return acc;
},{});
newMaindata.push(result);

console.log(newMaindata);

With reduce, you can do like following

    var Maindata = [{
      "name1": "string"
    }, {
      "name2": "string"
    }, {
      "name3": "string"
    }];

    var finalObj = Maindata.reduce((acc, cur) => {
      Object.assign(acc, cur);
      return acc;
    }, {})

    console.log(finalObj);

You could use Object.assign and spread the array elements.

var array = [{ name1: "string1" }, { name2: "string2" }, { name3: "string3" }],
    object = Object.assign({}, ...array);
    
console.log(object);
