For example, I create symlinks in /usr/local/bin (which is in the PATH), as follows: Instead of adding the bin directory to the PATH, you can create symlinks in one of the PATH directories. Node.js has two executables in its bin sub-directory: node (the standalone JavaScript engine) and npm (Node.js Package Manager).Unzip into a directory of your choice (e.g., /usr/local or /usr/local/lib). See " How to add a directory to the PATH". Add the "Node.js installed directory" to your PATH environment variable.zip)" and "64-bit" (e.g., " node-v12.16.1-win-圆4.zip" - 18MB) ⇒ Unzip into a directory of your choice, denoted as "Node.js installed directory". Goto Node.js download site ⇒ Choose "LTS" (Long-Term Support) ⇒ Download "Windows Binary (.Installation Installing Node.js In Windows Node.js is free, open-source, and runs under many platform (Linux, Windows, macOS).A huge number of libraries is available, which are managed by npm (Node package manager).You can program the client and server using the same JavaScript language.A Node.js server can handle thousands of concurrent connections without the burden of managing thread concurrency. This allows a Node.js app to run in a single process, without creating a new thread for every request. Instead of blocking the thread and wasting CPU cycles waiting, Node.js will suspend the first request, continue with the next request, and resume the operations when the response of the first request comes back. It provides a set of asynchronous non-blocking I/O functions (with new keywords async and await). Node.js uses asynchronous programming.Node.js runs the high-performance V8 JavaScript engine, the core of Google Chrome, outside of the browser.This is popular because you can use the same JavaScript language to program the client and the server. Node.js is commonly-used for programming web server, i.e., server-side JavaScript. Node.js is a JavaScript Runtime Engine that allows us to run JavaScript in standalone manner, without using a browser. Prior to Node.js, JavaScripts runs only under a web browser (such as Chrome, Firefox, and MSIE) bundled with a built-in JavaScript engine.
