// We can't just open a console on the ps4 browser, make sure the errors thrown
// by our program are alerted.

// We don't use a custom logging function to avoid a dependency on a logging
// module since we want this file to stand alone. We don't want to copy the
// log function here either for the sake avoiding dependencies since using
// alert() is good enough.

// We log the line and column numbers as well since some exceptions (like
// SyntaxError) do not show it in the stack trace.
