If you’ve worked with Node.js, you might have encountered a situation where requiring a file doesn’t automatically give access to the variables or functions defined in it. 🤔 Wondering why? Let’s break it down! 👇

🔍 How require Works in Node.js

In Node.js, every file is treated as a separate module, encapsulated within its own scope. This means:
1️⃣ Variables and functions in one file don’t leak into the global scope of another file.
2️⃣ For another file to access them, they must be explicitly exported using module.exports or exports.
