# `get()`
The get method returns the item at a given key or index. If the key or index does not exist, `null` is returned:
```js
const collection = collect({
firstname: 'Mohamed',
lastname: 'Salah',
});
collection.get('lastname');
// Salah
collection.get('middlename');
// null
```
```js
const collection = collect(['a', 'b', 'c']);
collection.get(1);
// b
```
You may optionally pass a default value as the second argument:
```js
const collection = collect({
firstname: 'Mohamed',
lastname: 'Salah',
});
collection.get('middlename', 'default-value');
// default-value
```
You may even pass a callback as the default value. The result of the callback will be returned if the specified key does not exist:
```js
const collection = collect({
firstname: 'Mohamed',
lastname: 'Salah',
});
collection.get('middlename', () => 'default-value');
// default-value
```
