I’m new to GoLang, coming from Node. A little late to the (definitely not functional) game and need some help understanding approaches, and perhaps just understanding…

I want to omit an item from a bunch of structs in an array.

lo.Map(twelveShuffledQuestions, func(q StaticQuestion) {
        return &StaticQuestionMinusCorrectAnswer{
            QuestionId:       q.QuestionId,
            QuestionType:     q.QuestionType,
            QuestionText:     q.QuestionText,
            PotentialAnswers: q.PotentialAnswers,
            Image:            q.Image,
        }
    })

All this is basically doing is showing a pattern how I would go about it in node (with the help of lo) – and no, this isn’t compiling as it cant infer the type args.

In terms of the data structure here, twelveShuffledQuestions is JSON backed, meaning it was imported and then marshalled:

jsonFile, err := os.Open("questions.json")
if err != nil {
    panic(err)
}
defer jsonFile.Close()
byteValue, _ := io.ReadAll(jsonFile)
localQuestionsToCheckAgainst := []StaticQuestion{}
json.Unmarshal([]byte(byteValue), &localQuestionsToCheckAgainst)

My question is how do I achieve this mapping of fields I want from the structs in the array?
