# `containsOneItem()`
|
|
|
|
The containsOneItem method returns true if the collection contains exactly one item; otherwise, false is returned:
|
|
|
|
```js
|
|
collect([1]).containsOneItem();
|
|
// true
|
|
|
|
collect({ firstname: 'Luis' }).containsOneItem();
|
|
// true
|
|
|
|
collect('value').containsOneItem();
|
|
// true
|
|
|
|
collect([1, 2, 3]).containsOneItem();
|
|
// false
|
|
|
|
collect({ firstname: 'Luis', lastname: 'Díaz' }).containsOneItem();
|
|
// false
|
|
|
|
collect().containsOneItem();
|
|
// false
|
|
|
|
collect([]).containsOneItem();
|
|
// false
|
|
|
|
collect({}).containsOneItem();
|
|
// false
|
|
```
