What is Node.js? ...isn't it just JavaScript?

[victorkochkarev]

In a browser JavaScript working with DOM elemetnts, reacting to user interactions and making HTTP calls to fetch data.
On a server it is processing multiple requests made by a huge ammount of users, calling other services, quering databases, checking user permissions, listeninig to message queues, and logging what ever needs to be logged - but it is the same JavaScript - not a big difference.

Best way I’ve heard that explained. Thanks!

cPython is a runtime, there’s other runtimes, IronPython, micro python, jython…

[roku_on_it]

Node is just syscall wrapper with JavaScript. That’s it

Edit:

Node worshippers crying because I summarized it to two words lol. Keep brainrotting 👍

V8 is the runtime, Node just gibes you access to the API of the operating system.

[fischi]

"if you know JS you need 90% of node" oh yes, it would be nice if it was true

[ethanwaldo]

Node.js and chrome are both built with the V8 engine by google!

[kirillzlobin]

Best explanation!!! Finally someone said this

[aresstavropoulos]

node is the runtime of javascript, if you only know javascript, you know 0% of node

[Daniel-ybwc]

I know JavaScript but for me to learned react was hard

[Kamel]

Im sorry, i couldnt hear over that massive toolchain you have XD

Learning node === learning js, jquery, babel, webpack, react, electron, etc. etc. the list goes on.

Does anybody remember Rhino? Where my OGs at?

"...and that's why its bad"
There, I put in the missing part.

Ok he is over simplifying thigs. Frontend and backend is not something.
When you have multiple services and they are communicating via kafka or http, and you need to mange fault tolrence with circuitebreaker, u have auth server with openid connect to auth every requesr and a gateway for clinent to interact, a discover service to discover other services, loadbalancer to balance load between services, a cache layer, u have to do distubuted transction with 2phase commit or saga, to find something you have to do distributed logging, then Db getting more lead u have to switch to slave and master dbs, multiple dbs for read and one for write you have to maintain consistency between them, you have to streams data so you do not block main thread, you have to deploy your app first create docker image and run in k8 cluster.

YEP ITS SAME THING

[pawelmod]

Haha, languages are mostly the same as runtimes? Laughing in Java(language with tons of running environment ) and .Net (different running environments for the same language and different languages first the same running env)

Cloudflare is a runtime. Edge is also a runtime. And here comes Bun as well 😂😂😅😅

Node.js and the browser use the same runtime in the Chrome browser. This gentleman is wrong. What he refers to, incorrectly, as a runtime is the APIs available. Node.js and the browser provide access to different APIs. The runtime deals with garbage collection and other housekeeping tasks that are required at runtime.
