will be helpful for those in need D3 would cope with either result format - it does slightly depend on what you want to do with it. Regardless, here is some example code for generating either format:
code :
var result = {};
array.forEach(function(i) {
    if (!result.hasOwnProperty(i.created)) {
        result[i.created] = 0;
    if (i.status === 1) {
        result[i.created] += 1;

var newArrayA = Object.keys(result)
                      .map(function(k) {
                          var o={};
                          o[k] = result[k];
                          return o;

var newArrayB = Object.keys(result)
                      .map(function(k) { return [k,result[k]] })

With these it helps Using Array.reduce, I am trying to count the elements that have the same value for a specific property. I want to put the result in an array of objects containing a property for the value of the grouped by property and another one for the count. How can I do this easily in javascript ? , You already got the what you want just transform it into an array
code :
const CATEGORY = {

const lessons = [{
  title: 'ohoho',
}, {
  title: 'hihihi',
}, {
  title: 'hello',

let count = lessons.reduce(function(acc, lesson) {
  acc[lesson.category] ? acc[lesson.category] ++ : acc[lesson.category] = 1
  return acc
}, {})

// transform count into what you want
let categoryLessonCount = [];
for (let cat in count) {
    'title': cat,
    'count': count[cat]


Objects with no '.Count' Property - use of @() (array subexpression operator) vs. [Array] cast

I wish this help you In PSv3+, with its unified handling of scalars and collections, any object - even $null - should have a .Count property (and, with the exception of $null, should support indexing with [0]).
Any occurrence of an object not supporting the above should be considered a bug.
