What is NPM?

Question

npm

I started learning NPM and didn't quite understand what it was. The references say it's a Node.js package manager. That is, a program that allows you to install node.js packages from the npm repository. For example gulp. It seems clear. But why install bootstrap or jquery with npm? These are the js, css libraries, but not the node.js package

Answer 1

A package manager is such a thing that allows you to download all sorts of programmer stuff from a remote storage to your computer. How it is good to call it - node.js packages, or something else, is not so important. It can be libraries, frameworks, anything, even the novel "Anna Karenina". You yourself can write anything, upload it to this repository and pull it with npm.
