npm is a package manager for the JavaScript programming language. It is the default package manager for the JavaScript runtime environment Node.js. npm stands for Node Package Manager. npm makes it easy to reuse code across projects, and to share code with others. It also provides a convenient way to keep your project dependencies up to date.
With npm, you can install and manage packages (libraries, frameworks, tools, etc.) that you use in your Node.js projects. These packages are published to the npm registry, which is a public repository of packages that anyone can use.
To use npm, you need to install Node.js on your system. Once you have Node.js installed, you can use npm to install packages from the command line by running npm install . You can also use npm to manage your project dependencies by creating a package.json file in your project directory, which specifies the dependencies that your project requires.
