I am so lost trying to make a program to display 1000 prime numbers using for/in loop with the numbers placed in an array. I would be happy if I could get for/in to display 0 - 1000 right now. Surely my instructor does not want me to type in the first 1000 prime numbers into an array.

var myArray = new Array(i = 0, i <= 1000, i++);
for (i in myArray)
 {
  document.write(myArray[i]);
 }

I don't know if this exactly meets the criteria, but...

var myArray = new Array();
for (i=0;i<=100;i++)
{
myArray[i]=i
}
for (i in myArray)
{
document.write(myArray[i]+"<br />");
}

However, I prefer using this:

var myArray = new Array();
for (i=0;i<=1000;i++)
{
myArray[i]=i
}
document.write(myArray);
