# `only()`
The only method returns the items in the collection with the specified keys:
```js
const collection = collect({
id: 12,
name: 'John Doe',
email: 'john@doe.com',
active: true,
});
const filtered = collection.only(['name', 'email']);
filtered.all();
// { name: 'John Doe', email: 'john@doe.com' }
```
```js
collect([1, 2, 3, 4])
.only([2, 12])
.all();
// [2]
```
> For the inverse of `only`, see the `except` method.
