Overview

Node.js is built on Google Chrome’s V8 JavaScript engine for high-performance execution.

Code Example

// V8 compiles JS to machine code\nconst sum = 1 + 1; // Extremely fast execution

Web Development Context

In modern web development, understanding The V8 Engine is crucial. Node.js is widely used for building APIs, real-time applications, and microservices. Mastery of this concept allows you to build efficient, scalable, and secure backend systems.
