Javascript "Empty Statement"

Spot anything wrong in the Javascript below?

var a=[];
//initialize array
for(int i = 0; i < 10; i++);
{
  a[i] = 100;
}

Values in array a will be:

[undefined, undefined, 100]

The semicolon at the end of the for loop forms an "Empty Statement". So a[i]=100; is actually outside of the for loop!
