In this part of the series, we will embed V8 into a C++ program, expose a function from C++ to JavaScript, and execute it. By the end of this tutorial, you’ll understand how to run JavaScript inside a C++ program using V8 and expose native C++ functions to JavaScript.

V8 is the high-performance JavaScript engine that powers Chrome and Node.js. In this guide, we’ll walk you through downloading, building, and running V8 from scratch. By the end, you’ll be able to execute JavaScript directly with V8, taking the first step toward building your own Node.js! 🚀

What is a module? A module is a block of code in a file. Modules are the bricks for structuring applications that are too big to efficiently maintain in a single file. They are the main mechanism to enforce information hiding by keeping private all the functions and variables that are not explicitly exported. The

The reactor pattern is the heart of Node.js. It is a specialisation of the previously discussed event demultiplexer algorithm. libuv, the non-blocking I/O engine of Node.js, implements the reactor pattern. So, how does it work? Let’s say there’s a single threaded application interested in reading data from a file (an I/O operation). The application kicks

Operating systems provide another native mechanism to handle concurrent, non-blocking resources efficiently. This mechanism is called synchronous event demultiplexer or event notification interface.
This component collects and queues I/O events that come from a set of watched resources, and block until new events are available to process.
