## Challenge Seed

<div id='js-seed'>

```js
// check if array is sorted
function isSorted(a){
  for(let i = 0; i < a.length - 1; i++)
    if(a[i] > a[i + 1])
      return false;
  return true;
}
// generate a randomly filled array
var array = new Array();
(function createArray(size = 5) {
  array.push(+(Math.random() * 100).toFixed(0));
  return (size > 1) ? createArray(size - 1) : undefined;
})(25);
var MinHeap = function() {
  // change code below this line
  // change code above this line
};
