How to Install Node.js and NPM on Windows

Node.js enables the execution of JavaScript code outside of a web browser, serving as a runtime environment. It’s built on Chrome’s V8 JavaScript framework, and it’s designed to be efficient and lightweight. With Node.js, you can use JavaScript to build server-side applications, command-line tools, and even desktop applications.

NPM, or Node Package Manager, is a package manager for Node.js. It’s a tool that helps you manage dependencies in your Node.js projects. With NPM, you can easily install and manage packages (which are basically libraries or modules of reusable code) from a central registry. These packages can be anything from frameworks and libraries to tools and utilities.

Node.js provides the runtime environment for executing JavaScript code, while NPM provides a way to manage packages and dependencies within Node.js projects. Moreover, they support each other in the sense that Node.js allows you to run JavaScript code, and NPM helps you manage the code and libraries that your Node.js projects rely on.

This is why installing both Node.js and NPM on Windows is necessary to effectively develop and manage JavaScript applications.
