Node Package Manager (npm) is a widely used open-source project for JavaScript. Using npm, developers can create a package of code and share them with other developers. A package is like a library where developers store reusable code in one place. The benefit of a package manager is that it helps you keep track of the different versions of your software and easily update them. It also makes it easier for other people to use your software by allowing them to install your package from a central repository.
