Have you ever thought about how Node.js was built back in 2009?

Do you know how the Chrome JavaScript Engine V8 works alongside the powerful cross-platform asynchronous I/O Libuv?

Or going even further, have you noticed how many JavaScript runtimes such as Bun, Deno, or Cloudflare Workers are going hype nowadays?

Is it that easy to build a JavaScript runtime from Scratch? Well, let's find out!

Today! You're going to build a complete JavaScript runtime that recreates how the Node.js system works by writing custom functions, integrating C++ functions, and using even threads.

Ah, and I brought surprises for you.

I've prepared a complete cloud environment for you to develop new features for your JavaScript runtime without having to set up a C++ environment or compile the V8 and libuv libraries.
