Introduction to Development Environments

Before we dive into the setup, let’s talk about what a development environment is. Simply put, it’s a collection of tools and software that allows you to write, test, and debug your code efficiently. Think of it as your coding workshop! 🛠️

A development environment is like a chef’s kitchen, equipped with everything needed to create a culinary masterpiece. 🍳
