PHP and Node definitely do.

Node doesn’t.

> parseInt('077')
77

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.

If the input string begins with any other value, the radix is 10 (decimal).

You seem to have missed the important phrase "in source code", as well as the entire second part of my comment discussing that runtime functions that parse user input are different.
