There are quite a few places in MCe where you can do code or scripting.

In general there are several types of scripting we support:

1. JavaScript
2. Liquid templates
3. SQL
4. JSON

All of these have extensive documentation, training courses and so on on the internet, so we aren't going to try to teach you any of these. Our documentation more focuses on the specifics of how to use within our system.

JavaScript is a programming language that lets you do a wide variety of things.

Liquid templates we use for formatting, such as formatting error messages, or to create IDs from other data

SQL is a powerful tool for accessing and editing your data

JSON is a form of defining a set of data and/or sending data to another system
