I have an array of two objects. When the user presses a button, I would like for the next value of a specific object property to be displayed. 

Here is my array: 

```
var allQuestions = [{
    question: "This is question number one",
    choices: ["one", "two", "three", "four"],
    correctAnswer: "two"
}, {
    question: "This is question number two",
    choices: ["dog", "cat", "bear", "lion"],
    correctAnswer: "bear"
}];

```

When the button is pressed, I would like for the next instance of "question" to be displayed. 

Here is my function to switch out the question:

```
function switchQuestion() {

    var singleQuestion = 0;

    if(singleQuestion >= allQuestions.length) {
        singleQuestion == 0;
    } else {
        singleQuestion == ""; // not sure what should go here
    }

    document.getElementById('question').innerHTML = allQuestions[singleQuestion].question;

}

```
