# Client Javascript

The **Client Javascript Node** is used to run any custom Javascript code in the main domain of your website. It is usually used for conversion tracking, but you can use it for any other purpose as well.

{% hint style="warning" %}
This is an advanced node. You need have the knowledge of Javascript to use this node.
{% endhint %}

To create Client JS node add the node and write any javascript code you would like to run. Code can contain dynamic parameters such as {{name}}, {{email}} etc and system would replace these with actual values for each user. [Please check templatization](/ai-builder/nodes.md#templatization-of-the-text) for more details on available variables.
