Day 116 of Learning MERN Stack

Hello Dev Community! 👋

It is officially Day 116 of my software engineering marathon! Today, I checked off another critical styling milestone in my React.js progression: implementing CSS Modules to build a clean, scoped component grid for a functional Calculator Interface! ⚛️🧮

When styling large enterprise applications, standard global style sheets often cause naming collisions. React CSS Modules elegantly solve this problem by scoping styles locally to the exact component file they belong to.

🧠 Breaking Down the Day 116 Calculator Architecture

As shown across my project source tree and browser layout checks in "Screenshot (258).png", "Screenshot (259).png", and "Screenshot (260).png", the setup applies modular data pipelines:

1. The Global Keypad Blueprint (App.jsx)

• Organized an explicit tracking array matrix inside the root application controller to handle sequential calculation pad definitions:

javascript
  let num = ["+", "-", "*", "/", "1", "2", "3", "4", "5", "6", "7", "8", "9", "0", "C"];
