# Supported and unsupported JavaScript entities

You can [use supported JavaScript functions](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/developer-center/conditions/supported-and-unsupported-javascript-entities/supported-javascript-functions.html "Supported JavaScript functions") when [creating a condition](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/developer-center/conditions/create-a-custom-condition.html "Create a custom condition").

For the unsupported JavaScript functions, we provide [alternative JavaScript examples](https://doc.sitecore.com/cdp/en/users/sitecore-cdp/developer-center/conditions/supported-and-unsupported-javascript-entities/unsupported-javascript-functions-and-alternatives.html "Unsupported JavaScript functions and alternatives"), when possible.
