## Functions

<span id="function-da-functor-dollargt-48161" />

### `$>`

```haskell theme={"theme":{"light":"github-light","dark":"github-dark"}}
$> : Functor f => f a -> b -> f b
```

Replace all locations in the input (on the left) with the given
value (on the right).

### `<&>`

```haskell theme={"theme":{"light":"github-light","dark":"github-dark"}}
<&> : Functor f => f a -> (a -> b) -> f b
```

Map a function over a functor. Given a value `as` and a function
`f`, `as <&> f` is `f <$> as`. That is, `<&>` is like `<$>` but the
arguments are in reverse order.

### `<$$>`

```haskell theme={"theme":{"light":"github-light","dark":"github-dark"}}
<$$> : (Functor f, Functor g) => (a -> b) -> g (f a) -> g (f b)
```

Nested `<$>`.

<span id="function-da-functor-void-91123" />

### `void`

```haskell theme={"theme":{"light":"github-light","dark":"github-dark"}}
void : Functor f => f a -> f ()
```

Replace all the locations in the input with `()`.
