parseInt not doing what Jim's did

My code never resulted in 10 or 1 the way it did for Jim.

var j = parseInt("012"); console result of j = 12

var j = parseInt("019"); console result of j = 19

Please look below the video at teacher's notes:

"Please note that newer browsers will return 12 for parseInt("012") and not 10. This is because the default second parameter is now 10 for decimal instead of 8 for octal."
