How could I randomise the order of questions being asked in my JavaScript quiz? [duplicate]

This question already has an answer here:

• How to randomize (shuffle) a JavaScript array? 26 answers

Currently I have this code which displays the questions on screen:

var questions = [
new Question("What is the answer to this question?", ["answer1", "answer2", "answer3", "correct answer"], "correct answer"),
new Question("question?", ["answer1", "answer2", "answer3", "correct"], "correct")
];

var quiz = new Quiz(questions);

I have researched various ways of randomising the order of questions, however none of them seem to work with the array I have. I was wondering how I would randomise the order of questions, whilst keeping the format I already have.
