## variableFromJSON()

The  `variableFromJSON()`  command extracts the value associated with a specific key from a JSON object and stores the result in a target variable. This command is useful for accessing values within a JSON object.

### Parameters

* SourceVariable Type: `var` Description: The variable containing the JSON object from which a value is to be extracted. It can be a variable that stores the JSON object or a direct value representing the JSON object.
* key Type: `value` Description: The key whose value is to be extracted from the JSON object. It must be a value that represents the key within the JSON object.
* TargetVariable Type: `var` Description: The variable where the extracted value will be stored. It must be a variable that will receive the value associated with the specified key in the JSON object.

### Command Flow

### Usage Example

Suppose the JSON object in  `jsonData`  is  `"name": "Alice", "age": 30`  and you want to extract the value associated with the key  `"name"` .

```javascript
// Variable definitions
jsonData = {"name": "Alice", "age": 30}
nameValue = ''

// Call the command to extract the value associated with the key "name"
variableFromJSON(jsonData, "name", nameValue)

// Return the extracted value through addResult
addResult(nameValue)
```

Since the value associated with the key  `"name"`  in the JSON object  `jsonData`  is  `"Alice"` , the  `variableFromJSON()`  command will extract  `"Alice"`  and store it in the variable  `nameValue` . The  `nameValue`  variable will be returned through  `addResult(nameValue)` , resulting in the following output:

```javascript
"Alice"
```
