Push an array into an array Javascript

Question

I'm new in JavaScript and I want to transform this array ["Banana", "Orange", "Apple", "Mango"], in this one [["Banana"], ["Orange"], ["Apple"], ["Mango"]], but when I try to do it, my browser freezes. I'm using this code:

<script>
var i = 0;
var fruits = ["Banana", "Orange", "Apple", "Mango"];
document.getElementById("demo").innerHTML = fruits;

function myFunction() {
    var fruits_aux = [];
    for (i=0; fruits.length; i++)
      fruits_aux.push([fruits[i]]);
    fruits = fruits_aux;
    document.getElementById("demo").innerHTML = fruits;
}
</script>

Be careful executing this code. Anyone can help me? Thanks

In your for loop, the condition always evaluates to true, hence, it becomes an infinite loop and the reason for your browser freeze.

for (i=0; fruits.length; i++)

should probably be

for (i=0; i < fruits.length; i++)
