Read: 06 - Node, Express, and APIs

What I’ve Learned

• Node.js is an event-based, non-blocking, asynchronous I/O runtime that uses Google’s V8 JavaScript engine and libuv library.
• the creator of Node (Ryan Dahl) took the V8 engine and enhanced it with various features, such as a file system API, an HTTP library, and a number of operating system–related utility methods.
• you can check that Node is installed on your system by opening a terminal and typing node -v. If all has gone well, you should see something like v12.14.1 displayed. This is the current LTS version at the time of writing.
• Node has excellent support for ECMAScript 2015 (ES6) and beyond. As you’re only targeting one runtime (a specific version of the V8 engine), this means that you can write your JavaScript using the latest and most modern syntax.
• Node comes bundled with a package manager called npm. To check which version you have installed on your system, type npm -v.
• These build tools come in all shapes and sizes, and you won’t get far in a modern JavaScript landscape without bumping into them. They can be used for anything from bundling your JavaScript files and dependencies into static assets, to running tests, or automatic code linting and style checking.
