What engine is Node.js14.8.0

Node.js is a JavaScript runtime environment for building high-performance, scalable network applications. Node.js, built on the Google V8 engine, provides powerful capabilities and is an essential part of modern web application development. Node.js 14.8.0 is the latest long-term support version of Node.js, which brings some new features and fixes some bugs.

The first version of Node.js was released in 2009, and since then it has become an important part of web application development. It is based on Google's V8 JavaScript engine, also developed by Google. The V8 engine is characterized by fast interpretation and execution of JavaScript code. The Node.js runtime environment provides many built-in modules and libraries that help developers achieve various tasks such as handling HTTP requests, file operations, database access, etc. In addition, various third-party modules and libraries can be installed by using NPM (Node Package Manager).

Node.js 14.8.0 is the latest reliable version of Node.js. It brings some new features, such as a major update of the V8 engine to version 8.4, improved performance and security, and enhanced support for ECMAScript (ES) 2020. In addition, improvements and fixes to built-in modules such as http, crypto, and fs are also included.

Some of the important updates in Node.js 14.8.0 include:

1. V8 engine version 8.4: The V8 engine is critical to the speed at which Node.js applications execute. After using V8 8.4 version, the performance and security of Node.js have been improved. In earlier versions, the code in the V8 engine was not optimized for execution, but in version 8.4, the optimized execution mode has been enabled, making Node.js more efficient.
2. BigInt: JavaScript is a dynamically typed language, and BigInt adds a new primitive type to the language: a type that can represent arbitrary-precision integers. BigInt can help developers better solve complex encryption-related problems by helping them handle precision issues that don't easily arise when large numbers are required.
3. Optional upgrade dependency update detection: When upgrading dependencies, you often need to double-check to ensure that other dependencies are still compatible with the updated dependency. In the Node.js 14.8.0 release, developers can use the npm update command with the --optional and --no-optional parameters to determine which dependencies are allowed to be updated and which dependencies should be prohibited.
4. Improved HTTP handling: Node.js’ built-in HTTP module has been improved and now has more default behavior and configuration options. In version 14.8.0, developers can configure Server objects using the new server.keepAliveTimeout() API to control long connection duration.
5. Other updates: In addition, Node.js 14.8.0 version also includes improvements and fixes to ES6 modules, Node.js fs modules, subprocess modules, crypto modules, etc. These improvements make the Node.js environment more reliable, stable and secure.

From this perspective, Node.js 14.8.0 is not just a simple update, but a new enhancement and improvement to this powerful platform. It's worth trying for developers who are familiar with Node.js and need to build high-performance, scalable web applications.
