"std" is a predefined variable in the QuickJS version you use. You
should upgrade to the latest release where "std" and "os" are only
defined with the "--std" option or in the REPL. In the older versions,
you can add the "--nostd" option to avoid the automatic definition of
"std" and "os".
Best regards,
Fabrice.
