How to show the number of users grouped by the month they signed up

Looking to showcase user counts based on the month they were created. Here's an example dataset:

[ 
  { name: 'user1', created: 'may' },
  { name: 'user2', created: 'may' },
  { name: 'user3', created: 'may' },
  { name: 'user4', created: 'may' },
  { name: 'user5', created: 'june' },
  { name: 'user6', created: 'june' },
  { name: 'user7', created: 'august' },
  { name: 'user8', created: 'august' },
  { name: 'user9', created: 'august' } 
]

The desired output should look like this:

may: 4
june: 2
august: 3

Any suggestions on how I can achieve this formatting?

Answer 1

Answer №1

To achieve this, one can utilize the reduce() method and output an object as the final result.

var data = [{"name":"user1","created":"may"},{"name":"user2","created":"may"},{"name":"user3","created":"may"},{"name":"user4","created":"may"},{"name":"user5","created":"june"},{"name":"user6","created":"june"},{"name":"user7","created":"august"},{"name":"user8","created":"august"},{"name":"user9","created":"august"}]

var result = data.reduce(function(r, e) {
  return r[e.created] = (r[e.created] || 0) + 1, r
}, {})

console.log(result)

Here is how you can get a sense of it:

let usersInMay = users.filter(user => user.created == 'may')

The variable usersInMay will either be null or an array. You can check its length to find out the number of users created in May.

usersInMay.length

You can iterate through all the months and determine the number of users created in each month.

One potential approach to consider is the following code snippet, however please note that it has not been tested so may require adjustments:

function extractData(month, dataset) {
       return let result = dataset.filter((entry)=>{
        return entry.created === month;
    })

If you're looking for a straightforward JavaScript solution, here's some code that can help:

var monthWithUsercount = {};

for (var i = 0; i < array.length; i++) {
    var number = array[i];
    monthWithUsercount[number.created] = monthWithUsercount[number.created] ? monthWithUsercount[number.created]+1 : 1;
}
//In this snippet, "array" holds the data with months and users.

console.log(monthWithUsercount);
