I'm trying to do a multiple choice question app but I can't figure out how I should create the node.js models using MongoDB(mongoose). For now, I have a Question model that I found from another similar question that I adapted to the recent syntax:

const Schema = mongoose.Schema;
import { AnswerOptionSchema } from './answer-option-schema';

const QuestionSchema = new Schema({
    question: {
        type: String,
        minlength: 10,
        maxlength: 1000,
    },
    answerOptions: {
        type: [AnswerOptionSchema],
        default: undefined,
    }
}, {
    timestamps: true
});

module.exports = Question = mongoose.model('Question', QuestionSchema);

So I try to understand how to create the other models
