How to correctly implement an array of objects in TypeScript?

Question

typescript

Hello.
Before the main question, I would like to ask a side question.
The purpose of the task is to make a quiz. That is, there is a question and n-th number of answer options.
To store all questions and quizzes, I'm going to use something like this

const questions: {question?: string, option1?: string, option2?: string, option3?:string, option4?: string}[] = [
    {
        question : "text of question 1",
        option1: "opt1",
        option2: "opt2",
        option3: "opt3",
        option4: "opt4"
    },
    {
        question : "text of question 2",
        option1: "opt1",
        option2: "opt2",
        option3: "opt3",
        option4: "opt4",
    },{},{},{},{},{},{},{},{}
];

there are doubts about this. Perhaps it's better to do something differently?

Other than that, I don't understand how to initialize this array in TypeScript. Because the number of properties for objects can be different.

Tell me pliz

Answer 1

interface Question {
  question: string;
  option1: string;
  option2: string
  ...
}
const questions: Question[] = [...]

although option${index} is a crutch, discover arrays
