Exploring JavaScript fundamentals! As part of my learning journey, I explored different ways to run JavaScript code in real-world environments. Understanding how and where your code executes is an important step for every developer. Here are 3 simple and commonly used ways to run JavaScript code: ✔️ Browser Console – great for quick testing and debugging ✔️ Node.js Terminal – useful for running JavaScript outside the browser ✔️ VS Code Terminal – efficient for development and project-based coding Each method has its own purpose, and learning all three helps build a strong foundation in JavaScript. #JavaScript #NodeJS #WebDevelopment #Coding #MERNStack #LearningJourney
