how to use an element's JS variables to get the current year?

[yotamguttman]

how do you use an element's variables to fetch information such as the current year?
I don't understand how to take a js code and break it into a variable's fields
code: const currentYear = new Date().getFullYear();
available fields in webstudio: name, type, value

I broke webstudio's AI when I told it to add a copywrite footer statement and have the year update automatically 😅

ps.
I hope no one has asked this question before, I couldn't find anything related. it's not necessarily related to webstudio but I just wanted to learn.
