  We're not talking about parsing in base 10, we're talking about parsing in base 8. I need to be able to tell if the parse succeeded or not, silently hiding errors is bad. The correct behaviour demonstrated in perl and python: $ perl -le 'print 07' 7 $ perl -le 'print 08' Illegal octal digit '8' at -e line 1, at end of line Execution of -e aborted due to compilation errors. $ python -c 'print 07' 7 $ python -c 'print 08' File "", line 1 print 08 ^ SyntaxError: invalid token

    Got to admit, I am disappointed that > parseInt("08", 8); returns 0 instead of NaN

      Returning 0 makes perfect sense. parseInt matches an integer from the beginning of the string, so it reads the 0 and then stops at the 8 because 8 is not a valid digit in base 8. >>> parseInt("123foobar", 10) 123

        Good point.
