### `uniqueArray(arr)`
This function returns an array with duplicates removed.
- **arr** an array to be deduplicated to have only unique values
```js
const { uniqueArray } = require("group-objects-array");
const arr = [{name: "John", age: 30}, {name: "Doe", age: 29}, {name: "John", age: 30}, {name: "Michel", age: 21}];
uniqueArray(arr);
```
returns
```js
[{name: "John", age: 30}, {name: "Doe", age: 29}, {name: "Michel", age: 21}]
```
### `isItemInArray(arr, item)`
This function checks if an item is in the given array.
- **arr** source array
- **item** item to be checked whether it is in the array
```js
const { isItemInArray } = require("group-objects-array");
const arr = [{name: "John"}, "world"];
isItemInArray(arr, {name: "John"}); // returns true
```
