Today A long time ago I implemented the CPF (Physical Persons Register) validation algorithm in javascript and rust to demonstrate how it is possible to not execute a single variable declaration (considering that receiving a parameter does not count as a declaration) using the method chaining programming style.

Hi, my name is Luiz Paulo, I'm a bachelor in information systems at UEMS and I've created this space to write about system architecture, programming and system administration by use of rust, javascript, shellscript and php as programming languages as well as linux and docker as technology.
