Overview of NPM (Node Package Manager).

What is NPM?

NPM, which stands for Node Package Manager, is a package manager for JavaScript. It is the default package manager for Node.js and is used to install, manage, and share packages or libraries of code for JavaScript and Node.js applications. NPM is an essential tool in the JavaScript ecosystem, making it easier for developers to handle dependencies, share code, and automate various development tasks.

Here is an Example to Understand NPM

NPM is like a kitchen pantry where you store and manage ingredients for a recipe (packages). You can easily access pre-made recipes (packages) to cook specific dishes (functionalities). It also helps you automate reminders (scripts) and ensures dietary safety (security) for your dinner party (project).

npm -v //this is for NPM
node -v //this is for Node
