- Node.js is an event-based, non-blocking, asynchronous I/O runtime that uses Google’s V8 JavaScript engine and libuv library.
It's a platform that JavaScript can run and excute.
The Node. js runtime is the software stack responsible for installing your web service's code and its dependencies and running your service.
npm is two things: first and foremost, it is an online repository for the publishing of open-source Node. js projects;
second, it is a command-line utility for interacting with said repository that aids in package installation, version management, and dependency management.
A plethora of Node.
Node allows developers to write JavaScript code that runs directly in a computer process itself instead of in a browser.
Node can, therefore, be used to write server-side applications with access to the operating system, file system,
and everything else required to build fully-functional applications.
Pair programming commonly involves two roles: the Driver and the Navigator.
The Driver is the programmer who is typing and the only one whose hands are on the keyboard.
Handling the “mechanics” of coding, the Driver manages the text editor, switching files, version control, and—of course writing—code.
The Navigator uses their words to guide the Driver but does not provide any direct input to the computer.
The Navigator thinks about the big picture, what comes next, how an algorithm might be converted in to code, while scanning for typos or bugs.
The Navigator might also utilize their computer as a second screen to look up solutions and documentation, but should not be writing any code.
