# getValue

Unwrap a value by calling it until it is no longer a function, then
return the result. It accepts a plain value, a signal reader, a
[memo](/memo) accessor, or any nested function-of-function. Useful
when authoring components or plugins that take an `Accessor<T>` /
`T | (() => T)` prop and want a single shape to work with.

## Arguments

| name    | type           | description                                    |
| ------- | -------------- | ---------------------------------------------- |
| `value` | `T \| () => T` | A plain value or a (possibly nested) accessor. |

**Returns:** `T` — the fully unwrapped value.

## Examples

### Unwrapping any accessor shape

Resolves the same helper across a plain value, a signal reader, a
memo-style function, and a deeply nested chain of functions.

```jsx
import { getValue, render, signal } from 'pota'

const a = signal(1)
const b = () => a.read() * 2
const deep = () => () => () => 'deep'

function App() {
	return (
		<div>
			<p>getValue(42): {getValue(42)}</p>
			<p>getValue(a.read): {getValue(a.read)}</p>
			<p>getValue(b): {getValue(b)}</p>
			<p>getValue(deep): {getValue(deep)}</p>
		</div>
	)
}

render(App)
```
