Bases: Extend List.contains so it is possible to search for substrings within list items

[WhiteNoise]

Right now, list.contains(value: any) performs an exact match between value and each item of the list.

In the case of lists of strings, it could be useful if the function would be extend, with an optional additional argument, to match substrings (partial match) within list items.

The FR below is even more general:

Base: Implement map, reduce, filter in formulas (lambda functions)

Use case or problem While working with lists and objects in Bases, there is a lack of higher order functions. This will open up possibilities to work with complex dataset inside the frontmatter. Proposed solution Lambda functions as (arg, arg2) => {statement1; statment2; return} Higher order functions as map(() => {}, [...]) map(() => {}, {...}) Related feature requests (optional) MOD-EDIT: removed for not being related to this FR to avoid confusion

This is redundant since filter will be implemented in v1.9.5
