Learning to code in JavaScript

I’ve been learning JavaScript at Code Academy.  I wrote the following bit of code to find all prime numbers from 1 to 100:
for (x = 3; x <=100; x = x +1)
{
var a = 0
var z = 0
for (y =2; y <= x – 1; y = y + 1)
{
z = x % y
if (z === 0) {a = a + 1} else {}
}
if (a === 0) {console.log(x)} else {}

After many months of inactivity, I have returned to Spadinasaur, this time testing Microsoft’s Windows Live Writer.  More later.
