Refactor Global Variables Out of Functions | Functional Programming | freeCodeCamp

📘 **"Crafting Timeless Code: A Journey Beyond Global Variables"** 📘

Embark on a transformative coding voyage as we embrace functional programming to its fullest, crafting solutions that stand the test of time.

📚 **Immutable Wisdom**:

Delve into the realm of unchanging truths where our code, like the steadfast oak, remains unaltered by the winds of global variables.

🛠️ **The Art of Refinement**:

Witness the evolution of our `bookList`, where each function meticulously adds or removes volumes without the merest ripple across the global scope.

🌟 **Principles in Practice**:

Our narrative unfolds as we apply two core principles: avoid mutating objects and declare all dependencies. Join us as we demonstrate these values, forging a path to coding enlightenment.

📖 **Harvesting Knowledge**:

Discover how to create and curate your own `bookList` with techniques that ensure its legacy endures through the `add` and `remove` functions, leaving the original list untouched, as if by an archivist's gentle hand.

🔗 **Subscribe for Time-Honored Coding Techniques**:

Subscribe to our channel where the code flows like ink on parchment, each function a chapter in a story of timeless best practices. Hit play, and watch as we rewrite the annals of `bookList` management, each function a testament to the enduring principles of functional programming. Share in the legacy, absorb the wisdom, and join us for more sagas of immaculate coding.
