Day 110 of Learning MERN Stack

Hello Dev Community! 👋
It is officially Day 110 of my software engineering marathon! Today is Day 2 of my intense React.js transition, and I have unlocked the exact secret that makes modern declarative frameworks superior to traditional static web design: Dynamic Expression Embedding and Multi-Instance Component Reuse! ⚛️✨
In vanilla web development, injecting dynamic variables into the DOM required selecting elements via IDs and messing around with .innerText or template strings. React completely replaces this with elegant evaluation blocks.
🧠 Deconstructing the Day 110 Declarative Data Architecture
As compiled live inside my system workspace across "Screenshot (248).png" and "Screenshot (249).png", the engine handles dynamic template computations cleanly:
1. Evaluation Blocks & Inline Object Styles (Random.jsx)
- Inside the isolated functional component
Random, I embedded raw JavaScript calculations directly inside the render cycle ("Screenshot (248).png"):
javascript
let num = Math.floor(Math.random() * 100);
