# `first()`
The first method returns the first element in the collection that passes a given truth test:
```js
collect([1, 2, 3, 4]).first(item => item > 1);
// 2
```
You may also call the first method with no arguments to get the first element in the collection. If the collection is empty, null is returned:
```js
collect([1, 2, 3, 4]).first();
// 1
```
