JavaScript on the Server

👉 Ever wondered why JavaScript isn’t just for the browser anymore? In this kickoff video, we’ll explore the rise of server-side JavaScript — from its humble beginnings in Netscape (1995) ⚡️ to the game-changing release of Node.js in 2009.

💥 You’ll learn:
- A quick history of JavaScript and how it went from a “sidekick” language to running the backend of the web.
- What makes Node.js special: the V8 engine, event-driven architecture, and non-blocking I/O.
- Why developers love using one language across the full stack (frontend, backend, and even databases!).
- Real-world use cases: APIs, real-time apps, CLI tools, microservices, and even IoT robots 🤖.

⚡️ Plus, we’ll demo how the same console.log works in the browser and in Node.js, and spin up a tiny web server that responds with "Hello from the server!".

👉 Perfect if you’re new to Node or curious about why companies everywhere are betting big on JavaScript beyond the browser.

👉 JavaScript is single-threaded… so how does Node.js handle multiple tasks at once without freezing up? ⚡️

In this episode, we break down the event loop and explore the core async patterns every Node developer needs to know:

💥 You’ll learn:
- The single-threaded event loop and how Node.js handles I/O using libuv.
