[](https://i.stack.imgur.com/3IuR3.png) | do something like this, first sort the array, then loop over it a take what you want
```
let arr = ["17: Mega Sena", "16: Mega Sena", "15: Mega Sena", "11: Dia de Sorte", "11: Dia de Sorte", "16: Mega Sena"]
var sorted_arr = arr.slice().sort(); // You can define the comparing function here.

58,701,955 | I have this array (it is an example) and I'd like to get the duplicate items and push it into another array.
```
let arr = ["17: Mega Sena", "16: Mega Sena", "15: Mega Sena", "11: Dia de Sorte", "11: Dia de Sorte", "16: Mega Sena"]
```
I tried to loop with `foreach` and got this:
My code:
```
var counts = [];

] | The `counts` object has strings as it's indexes. Use `Object.keys` to get a list of keys.
[](https://i.stack.imgur.com/3IuR3.png) | `counts` should be an object, not an array, since the keys are strings, not integers.

let arr = ["17: Mega Sena", "16: Mega Sena", "15: Mega Sena", "11: Dia de Sorte", "11: Dia de Sorte", "16: Mega Sena"]
var counts = {};
arr.forEach(function(x) {
counts[x] = (counts[x] || 0)+1
