# Has Local Value

The **Has Local Value** node checks whether a specific key exists in the local storage. It is a quick and efficient way to verify if a particular piece of data has been saved previously.

**Inputs**

* **Key (String)** : The unique identifier for the data you want to check.

**Outputs**

* **Result (Boolean)** : Returns `true` if the key exists in the local storage, and `false` otherwise.

**How It Works**

This node queries the local storage using the provided **Key** . If the key exists, it means the associated value has been saved previously, and the node will return `true`. If the key does not exist, the node will return `false`.
