вот так я загружаю в викторине в компоненте монтировал

loadQuiz = () => {
    const { currentQuest } = this.state;
    this.setState(() => {
      return {
        questions: Quizdata[currentQuest].question,
        options: Quizdata[currentQuest].options,
        answer: Quizdata[currentQuest].answer,
        pictures: Quizdata[currentQuest].picture
      };
    });
    console.log(this.state.answer);
  };

я хочу, чтобы он случайно выбрал 5 вопросов, которые не повторялись, и отображал один за другим , в этой песочнице у меня есть работа по загрузке существующих вопросов. https://codesandbox.io/s/reverent-saha-411y3

Answer 1

Попробуйте эту логику c, но вам нужно убедиться, что вы перевели копию исходного массива в другой массив, чтобы ваш первоначальный набор вопросов не был поврежден, как этот newQuestions = [...questions].

var myArray = [1,2,3,4,5,6,7,8,9,10];

var newArray = [];
for(let i=0; i<5; i++) {
  let index = Math.floor(Math.random()*myArray.length);
  newArray.push(myArray[index]);
  myArray.splice(index, 1);
}
console.log(newArray); 

Позвольте мне знаю, поможет ли это.
