Creating a String Function in Haskell Code

Can you implement the string function in the code please (In Bold)? (Haskell)

Code: module JSONTransformer (Transformer, field, select, pipe, string, int, equal, elements) where import JSON

Answer:

To implement the string function in Haskell code, you can define a function called 'string' that takes a JSON value as input and returns a list of JSON values.

The 'string' function in Haskell code is designed to handle JSON values and extract string values from them. By defining the 'string' function, you can easily manipulate and transform JSON data containing strings in your program.

In Haskell, the 'string' function can be implemented using pattern matching to check if the input JSON value is a string or not. If it's a string, the function should return the string value in a list. Otherwise, it should return an empty list.

Here is an example implementation of the 'string' function:

        string :: JSON -> [JSON]
        string (JString s) = [JString s]
        string _ = []
    

In this implementation, the 'string' function checks if the input JSON value is a string using pattern matching. If it is, the function returns a list containing the string value. If not, it returns an empty list.
