# Functions

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/serverless/functions/get-function-instance/) now.

The Function group in Catalyst is created and defined through either Catalyst's Online editor or Command Line Interface (CLI). The functions in a function group can be executed in a testing environment as well as in the production environment.

### Get a Component Instance

The functions reference can be created by the following method which would not fire a server side call.

```javascript
//Get a function instance
var functions = catalyst.function;

```
