• 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)
