Answer 1

This is javascript, but you're using int in your loop declaration? Try replacing those with var instead.

Answer 2

In my case, the error was caused by using let in the loop. Old browsers like Firefox 38 doesn't support let.

Replacing let by var solved the issue.

Answer 3

Change int i and int j to var i and var j.
