While the core SIL language provides the basic programming constructs, the Standard Library is what makes SIL a powerful tool for Jira automation and customization. These functions are an integral part of the language, though some are specifically tied to particular Power Suite apps.

## How to read function documentation

In this library, each function is documented using a consistent format to help you quickly find the information you need:  


| **Function name** | The exact name to use in your code. |
| --- | --- |
| **Description** | A brief explanation of what the function does. |
| **Parameters** | What input the function accepts:<br>- Name and type of each parameter
- Whether it's required or optional
- Description of what the parameter is used for |
| **Return type** | What the function returns:<br>- The data type of the return value
- Description of what the returned value represents |
| **Examples** | Sample code showing how to use the function. |
| **See also** | Links to related functions or relevant documentation. |
