1.Node.js is a cross-platform runtime environment that allows you to create server-side and networking applications. Some key features of Node.js include: Asynchronous and Event-Driven: The Node.js library’s APIs are all asynchronous (non-blocking) in nature. A server built with Node.JS never waits for data from an API. After accessing an API, the server moves on to the next one �Single-Threaded: Node.js employs a single-threaded architecture with event looping, making it very scalable
2. npm stands for Node Package Manager. It is a package manager for JavaScript programming language and is the default package manager for the JavaScript runtime environment Node.js. npm is used to install and manage packages (libraries, frameworks, tools, etc.) that you can use in your JavaScript projects
3. There are many popular  Node.js frameworks and libraries that can be used to build web applications. Some of the most popular ones include Express.js, Socket.io, Mongoose, Nodemailer, Passport.js, Async.js, GraphQL and Axios . These frameworks and libraries provide a range of features and functionality that can help developers build web applications more efficiently.
4. V8 is the name of the JavaScript engine that powers Google Chrome. It's the thing that takes our JavaScript and executes it while browsing with Chrome.
5. Express.js is a minimal and flexible Node.js web application framework that provides a robust set of features for web and mobile applications. It offers a range of HTTP utility methods and middleware that can help developers create a robust API quickly and easily. Express provides a thin layer of fundamental web application features, without obscuring Node.js features that developers know and love
