# Code

> Execute custom JavaScript code to perform complex logic and data processing

#### What It Does:

* Runs custom JavaScript code during the call
* Manipulates variables and performs calculations
* Implements complex decision logic
* Processes and transforms data

#### Key Features:

* **JavaScript Execution**: Run custom logic and calculations
* **Variable Manipulation**: Create, modify, or calculate variables
* **Conditional Logic**: Implement complex decision trees
* **Data Processing**: Transform or validate data
* **External Libraries**: Use built-in utility functions
* **Error Handling**: Try-catch blocks for robust code

#### Configuration Options:

* **Code Editor**: Write and edit JavaScript code
* **Input Variables**: Variables available to the code
* **Output Variables**: Variables created or modified by the code
* **Error Handling**: How to handle code execution errors

#### Testing Tips:

* Test with various input data scenarios
