Node 12

Node 12

Node 12 is a version of Node.js, an open source server environment that allows for the execution of JavaScript code outside of a web browser. Node.js utilizes an event-driven, non-blocking I/O model which makes it lightweight and efficient.

Node 12 is the twelfth major release of Node.js and it includes several new features and improvements over the previous versions.

New Features in Node 12

• Improved Performance: Node 12 includes V8 v7.4 which brings performance improvements and reduced memory usage.
• ECMAScript Modules: Node 12 now supports ECMAScript modules natively without the need for the --experimental-modules flag.
• Diagnostic Reports: Node 12 includes a new feature called Diagnostic Reports which provides detailed information about crashes and other issues in production environments.
• Worker Threads: Node 12 adds a new experimental feature called Worker Threads which allows for true multi-threading in Node.js.

// Example of using ECMAScript modules in Node 12

// Importing a module
import { add } from './math.js';

// Using the imported module
console.log(add(2, 3)); // Output: 5

Overall, Node 12 provides several new features and improvements that make it a great choice for building scalable and efficient server-side applications using JavaScript.
