#  makeInitializer()

```ts
function makeInitializer(fn): Initializer;
```

Defined in: [warp-drive-packages/core/src/signals/reactivity/internal.ts:27](https://github.com/warp-drive-data/warp-drive/blob/c4a56d51ea580688972bd7706dd4dc9bdfa6f53a/warp-drive-packages/core/src/signals/reactivity/internal.ts#L27)

Wraps `fn` so that a signal can recognize it as a lazy initializer
for its value rather than the value itself, deferring the call to
`fn` until the signal is first accessed.

## Parameters

### fn

() => `unknown`

## Returns

`Initializer`
