How to use `elemIndex` from Data.List on Strings in PureScript?

Question

The problem I am trying to solve looks like this, take an address string:

"Street, City, State"

and split it into ["Street", "City", "State"], in order to do this I am trying to use elemIndex like:

elemIndex "," "a, b, c"

but I realize that this violates the type signature of

elemIndex :: String -> List String -> Maybe Int

and tried a variation with characters because [Char] and String are the same type.

elemIndex ',' "a, b, c"

but that results in a type error as well. Which function is appropriate to do this if elemIndex is not appropriate to solve this problem.

I think you are looking for the split function. The type definition is as follows:

split :: Pattern -> String -> Array String

You should use it as follows:

split (Pattern ", ") "Street, City, State"
