JavaScript runs on browser in Browser's JavaScript engine(V8 in Chrome, Spidermonkey in firefox, etc)
Somebody ported V8 engine and made it installable in server. This is what is Node.js.
You can run JavaScript in node.js(instead of the browser)
Even servers can be written in node.js(with libraries like express.js)
With Node.js unlimited possibilities arose
Thats how Node.js Packages were born(now known as npm packages)
These are just some javascript files published into some registry(like a telephone registry but for js packages)
npmjs.com is a good package registry widely used
In node.js, then came the need to manage these packages(as people wanted to use packages written by other folks)
so package managers like npm(by npmjs.com) and yarn(by facebook) was born (// These tools are similar to Maven in Java)
