JavaScript do you need to know to use Node? 5. Differences between Node and the Browser 6. The V8 JavaScript Engine 6.1. Other JS engines 6.2. The quest for performance 6.3. Compilation 7. Run Node.js scripts runtime environment. It is a popular tool for almost any kind of project! Node.js runs the V8 JavaScript engine, the core of Google Chrome, outside of the browser. This allows Node.js to be very performant lightweight server to create asynchronous HTTP microservices. Socket.io, a real-time communication engine to build network applications.

What is Deno “Deno 是基于 V8 并采用 Rust 构建的，一个简 单、现代且安全的 JavaScript 和 TypeScript 运行时环境。” Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. ©hijiangtao Deno / 基于 V8 V8 是一个由 Google 开发的开源 JavaScript 引擎，其在运行之前将 JavaScript 编译成了机器代码 ，而非字节码或是解释执行它，以此提升性能。更进一步，使用了如 Inline Cache 等方法来提高性 能。有了这些功能，JavaScript 程序与 V8 引擎的速度媲美二进制编译。在 Deno 中，V8 引擎用于 执行 JavaScript Rust 构建 Rust 是由 Mozilla 主导开发的通用、编译型编程语言。设计准则为 “安全、并发、实用”，支持函数 式、并发式、过程式以及面向对象的编程风格。Deno 使用 Rust 语言来封装 V8 引擎，通过 libdeno 绑定，我们就可以在 JavaScript 中调用隔离的功能。 ©hijiangtao Deno / 简单 1. 天生支持 TypeScript - 使用 Deno

disambiguate it from other nodes.” https://github.com/joyent/node/wiki/FAQ Runs on top of Chrome V8 (see next slide) Implemented in C++ and JavaScript Supported on Linux, Mac OS X and Windows Created application can benefit from asynchronous, non-blocking I/O application is not compute-intensive V8 engine is fast enough prefer callback or actor models of concurrency over thread-based approach with Chrome V8 From Google Used by Chrome browser and Node.js Implemented in C++ Currently supports ECMAScript 5 Node adopts the JavaScript syntax supported by V8 so will support ES6 when V8 supports
