# unset

Learn how to delete the key and value at a given path.

This method chains an `unset` operation to the patch, which deletes a key and value at a specified path.

The difference between [`clear`](clear) and `unset` is that `clear` clears the value preserving the path, while `unset` deletes the path.

> **Fail-safe operation**
>
> This operation does not fail if the path does not exist.

## Signature

```ts
patch.unset(path: string): Patch

```ts
patch.unset('preferences.color');
```

## Parameters
