The "mode" value on the web is a "whole number". But sometimes you need an "octal". "number is the correct type in javascript.

Thank you.

Octals (0755) are integers, so I don't really get the problem. The type number includes integers and floating point numbers, so why would number be more appropriate than integer?

He thought that the "integer" type does not exist in js and the official type was "number".

I found that it uses the word "integer" in js:
Number.isSafeInteger(0o777) -> true
Thank you.
