JavaScript Code:

function max_of_three(x, y, z) 
 {
  max_val = 0;
  if (x > y)
  {
    max_val = x;
  } else
  {
    max_val = y;
  }
  if (z > max_val) 
  {
    max_val = z;
  }
  return max_val;
}

console.log(max_of_three(1,0,1));
console.log(max_of_three(0,-10,-20));
console.log(max_of_three(1000,510,440));

JavaScript: Tips of the Day

How to insert an item into an array at a specific index (JavaScript)?

What you want is the splice function on the native array object.

arr.splice(index, 0, item); will insert item into arr at the specified index (deleting 0 items first, that is, it's just an insert). In this example we will create an array and add an element to it into index 2:

var arr = [];
arr[0] = "Jani";
arr[1] = "Hege";
arr[2] = "Stale";
arr[3] = "Kai Jim";
arr[4] = "Borge";

console.log(arr.join());
arr.splice(2, 0, "Lene");
console.log(arr.join());
