# removeFromContext

## Syntax

`removeFromContext(key, value, mode)`

## Description

Removes data from the Context object: either a key-value entry or a specific value within an array stored under that key.

**Parameters:**

* `key`: `string` — the key in the Context object.
* `value`: `string` — the value to remove if the mode is set to `"array"`.
* `mode`: `"simple" | "array"`:
  * `"simple"` — deletes a key-value entry.
  * `"array"` — removes a value from the array.

**Returns:** `void`

## Example

```js theme={null}
// Delete a key-value entry
removeFromContext("user.city", "", "simple");

// Remove a specific value from an array
removeFromContext("user.purchases", "book", "array");
```
