### Remove duplicated elements in array in JS (ES6)

We have the following case:

```js
// we have an array with some duplicated elements
let data = [1, 2, 3, 1, 4, 2, 6, 5, 6, 2];

// we want to remove duplicated elements and get the result like below
[1, 2, 3, 4, 6, 5];
```

### Set

By using `Set`and spread syntax, we can easily achieve this:

```js
// using set and spread syntax
data = [ ...new Set(data) ];

console.log(data);
> [1, 2, 3, 4, 6, 5];
```
