This is your sign to try filter()
In Notion Formula, filter() function allows users to extract specific items from a list based on defined conditions. In this blog post, we will explore the structure of the filter() function, break down how it works, and provide examples to illustrate its utility.
For this guide, I referenced the Notion Formula documentation and added my own examples and explanations.
Summary

or
list.filter(condition) | Designed to return a list of values that meet certain criteria | filter([80, 150, 200], current > 100)

filter() Formula
How filter() works
The filter() function iterates through each item in the provided list, checks it against the condition, and returns a new list that contains only those items that meet the specified criteria.
The syntax for the filter() function is as follows:
filter(list, condition)
