PHP and Node definitely do.

Node doesn’t.

> parseInt('077')
77

1. If the input string, with leading whitespace and possible +/- signs removed, begins with 0x or 0X (a zero, followed by lowercase or uppercase X), radix is assumed to be 16 and the rest of the string is parsed as a hexadecimal number.
2. If the input string begins with any other value, the radix is 10 (decimal).
