    there is 0o for octal.. if use just 0 and accidently have a 8 or 9, it becomes a normal decimal while 0o will throw an error. as said before, you have 0b = binary 0o = octal 0x = hexa

    oh no, 078 throws "78" and 077 throws "63".

    077/078 is not a really a gotcha. It seems to follow Javascript's patterns for type coercion. Some numbers can evaluate as octal numbers, and some can't. If a string starts with 0 and contains only numbers 0 through 7, then it is evaluated as octal. If the string starts with 0 and has any number above 7 (not octal), then it evaluates as decimal. It's not a mystery, it actually makes some sense even if octal in Javascript is not normally used.

    On the rare occasion when you need to set file permissions from JS you will finally appreciate it :D
