# `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
|
|
```
