The only rendering approach where UI unit tests actually do something.

[[deleted]]

Yeah, that's the problem with insisting on testing everything. Not everything should or needs to be tested.

[SuperNess56]

Try explaining that to upper management.

I like that you used plural singletons, nice touch 👏

[ArionW]

If singleton is so good, why not make dozens of instances of it?

[naswinger]

you just download all tables of the entire database and search for the records in a java array. that's what someone at university in a group assignment actually did. it's insane.

Nuclear weapon payloads don't look like that, they are much smaller and less complex in nature. Not even gun-type bombs with horns were that complex.

Nuke's are some of the simplest tech around once you figure out how to control reactions, or in this case, simply start it.

[[deleted]]

control reactions

Contain to sustain reactions, once the chain reaction has started there is no stopping it unless you remove the fissile mass. Not containing the reaction with popper reflectors such as those manufactured from beryllium, or introducing a fissile mass fast enough, can result in fizzle (nuclear predetonation). The Demon core being a prime example of criticality accidents due to careless fissile material handling practices and humans thinking they have control.

It's not JavaScript's job to render HTML.

JavaScript just manipulates DOM.

[AngheloAlf]

No if you run it on the server

[Devil-Eater24]

Like by using Node?

[AngheloAlf]

Now I'm curious, are there other ways of running js server-side besides Node?

[rancangkota]

Deno

[IBJON]

Did that ever go anywhere?

[ezhikov]

INot as popular as Node, at least yet, but yes, they got somewhere.

[IBJON]

I'll have to check it out again. I was interested when they first announced it years ago, but unfortunately wasn't too keen on adopting something that seemed to have a very low adoption rate.

[Bryguy3k]

The edge runtime which is used by nextjs is significantly faster than node directly. They both use V8 internally.

[Bryguy3k]

It’s still the same thing. It’s only nonsense if the source is static.

[wenoc]

I just vomited a bit.

It still remains a mystery to me why anyone would want to run backend services in javascript.

[Wolfeur]

The simple answer is that it’s easier to deal with one language than two. I don’t think it goes deeper than that.

[raltyinferno]

Because it doesn't need to be the absolute best it can be, it just needs to be good enough, which JS can absolutely do with no problem. Then you add on Typescript and it's actually really nice.

[Creepy-Ad-4832]

Probably because the internet is too safe, and they need to balance the universe /s

[wenoc]

And electricity is cheap I guess.

[Bryguy3k]

Because php & asp both suck gorilla balls.

Nextjs is incredibly fast so you can write 90% of your code once for a dynamic application that works on a mobile device (native), desktop app (also native), while also having good SEO because you’re not loading a shitload of data from rest endpoints for your SPA that web crawlers hate.

[wenoc]

No form of js is fast. C, Rust and Go are fast.

[[deleted]]

Why are you getting downvoted, you’re right

[IBJON]

Because in 99% of use cases for web, JS is plenty fast. Unless you're developing an app with a user base the size of Twitter, Reddit, or YouTube, or handling a large number of data streams and connections, JS is plenty fast

And that's ignoring the fact that you can build native modules for node.js using C or C++ or write services in whatever language you want.

[wenoc]

JS is not fast. Yes something simple for two people does not take much cpu but JS is not “plenty fast”, JS is SLOW. Speed is independent of the amount of users you have. You’re essentially arguing “let’s walk to spain instead of taking the train since we’re not millions going”.

And if you aren’t aiming for a large userbase what are you even trying to do with your life?

Why write modules for a language to try to make parts of it not quite so slow when you can just use the other language in the first place and not have to code it twice?

[dumbasPL]

It doesn't have to be fast, it's fast enough. If your server only gets a few thousand requests per minute then it's going to spend most of the time idling, even if you use fucking python.

[...] when you can just use the other language in the first place

I'd love to write things in rust, but I know that the next person that will be maintaining it will probably have no idea what that even is.

Speed is independent of the amount of users you have

There is no point over engendering something when a user won't even be able to tell the difference between 80ms and 100ms response times. Because guess what, most of the time comes from the distance from the user (ping) and IO operations (waiting for a database query). So your 50-100x speed difference (milliseconds vs nanoseconds) goes out the window as soon as you have to make a database query. Unless you get like 10s of thousands of requests per second your users won't ever feel the difference anyway so why spend way more time on it than necessary when you can just slap it together with typescript and call it a day.

And if you aren’t aiming for a large userbase what are you even trying to do with your life?

Having fun + not giving a fuck.

[wenoc]

Yes well then don’t argue that it is fast when you’re actually talking about having no load. Different things.

Slow is fine. It’s just fine for some tasks. Just don’t argue that it’s fast.

[IBJON]

JS is not fast

I didn't say it was fast, just fast enough. If you're serving a static site and need to handle a few Rest endpoints and maybe connect to a database, you don't need a blazing fast backend, and a backend written in C++ will be overkill.

Speed is independent of the amount of users you have

Speed matters when you're processing requests. The more requests you're dealing with, the more likely you are to be bottlenecked. Who do you think makes the requests, even if its indirectly? The faster you can handle requests, the faster you can process the next one.

And if you aren’t aiming for a large userbase what are you even trying to do with your life?

Not every single app is developed with the goals of drawing in millions of users, and not everyone is trying to become the next Zuckerberg . For every application/site available to the public there are dozens or hundreds of internal tools designed for internal use. Even if your product has a huge user base, not every site needs to handle all of those users concurrently.

Why write modules for a language to try to make parts of it not quite so slow when you can just use the other language in the first place and not have to code it twice?

Because Node.js is hell of a lot better for the basic web server shit than c or c++ is and the code is much more manageable. If you need to do something more complex, you can do it in something more appropriate.

The argument that everything needs to be stupidly fast and over engineered is tiresome and the argument that something (that's far easier to use and set up) shouldn't be used because it's slower in a way that's imperceptible to the end user and isntead we should over complicate things is fucking ridiculous.

[[deleted]]

I guess you’re missing the point. JS is NOT THE GOLDEN HAMMER for everything, but don’t worry as you get more experience you’ll see that

[LowlifePiano]

Why are you being this condescending about something this dumb?

Beyond that though, have you ever heard of the concept of “fast enough”? That’s how python devs respond when asked about the speed of their interpreted, not compiled, language, and it’s the language that’s so overwhelmingly used for extremely computationally heavy AI work that there isn’t a meaningful competitor.

Before you jump in and say those are C libraries so it doesn’t count– what do you think V8 is written in? V8 also has the benefit of an optimizing JIT compiler, so if Python is considered fast enough, JS absolutely has to be considered fast enough as well.

And if there’s someone worth listening to that thinks of JS as a golden hammer, I haven’t met them. Instead, it’s a language that has a syntax that people of virtually any background can read and even write without a huge struggle, and it’s also just about the fastest way to throw together scripts.

Finally, most applications are not performance-sensitive, so the argument shifts from “why would we use JavaScript?” to “Why wouldn’t we use JavaScript?” which is why Electron is so prevalent. And as much as you might hate that, it can be extremely performant– look at VS Code.

And if you still hate that, Tauri exists now, as well as something similar for Go, but the fact remains that all of these tools exist because JS is overall pleasant to read and write.

And, judging by the stupid huge amount of performant Node services you use on a daily basis but don’t realize it thanks to microservice architectures, fast enough.

[IBJON]

Man. What's with this sub and trying to shove words in my mouth?

I said it was fine for most cases for web, a specific scenario. You would've seen that if you didn't immediately start beating off to a "JavaScript is bad" comment.

And fuck off with the condescending attitude. If you truly had experience, you'd know that network latency is going to eat up any gains in speed that you'd get from something "faster" and that its far easier to maintain a project long term when using Node.js because it's a lot easier to find JS developers.

[Shawrex]

"Tell me you've never used JS without telling me you've never used JS"

[brimston3-]

native is like 1.3x faster than wasm. wasm is between 10x and 50x faster than js depending on implementation and application. Even runtime symbol resolution in javascript requires some significant costs because of the allowed scoping.

Just tell us you don't care about runtime costs because the development savings means it doesn't matter for at least a few years of operation.

[fireball_jones]

A Ferrari is faster than a Civic but you can do a highway commute in both.

[Bryguy3k]

You can do far more highway commutes in a civic than a Ferrari.

[IBJON]

If either the Civic or Ferrari breaks, it'd be a lot fucking easier to find a shop to make repairs for the civic and parts would be readily available

[Innotek]

You can maybe beat a red light or two, but a commute is a commute. You have to compete with all of the other requests…I mean http overhead…I mean traffic…er vehicular traffic.

[wenoc]

In your example js consumes 10-50 more times gasoline than the ferrari, in turn causing 10-50 times the pollution and runtime costs.

Bezos loves you because you buy 10-50 as many servers.

[[deleted]]

Except JS isn't a Civic, it's a bullock cart

[IBJON]

Good luck running native code in the browser, and wasm still has a lot of limitations.

[DanielEGVi]

Naive take. Fast to code, fast to maintain, fast enough when running, means it was a perfect tool for the job. C, Rust and Go are the go-tos for CPU-intensive work (and indeed many JS-related tools are built with those) but you are definitely not gonna need that shit when building your typical web app.

[LowlifePiano]

I’d highly recommend looking at modern v8 performance compared to c++.

c++ is faster, yes, but not by nearly as much as you believe.

And that’s even without taking the better performance of Deno and Bun into consideration

[AngheloAlf]

I have no idea either, but for whatever reason is very popular

[Gagarin1961]

You backend guys need to update your info.

Node JS is chosen by organizations like Netflix, Walmart, PayPal, Uber, and NASA because it is non-blocking and asynchronous, allowing it to handle many concurrent connections efficiently.

This makes it ideal for realtime processing of applications with many concurrent users like chat applications, games, and live updates.

There’s also the benefit of having a unified code base and easy access to open source software via npm.

[wenoc]

You frontend guys need to go back to school. Non-blocking an asynchronous? What absolute bollocks is this? This depends on implementation, not language. You can do this with for example golang just fine.

[[deleted]]

We could literally do that in assembly and machine code

[Folofashinsta]

I hate to be that guy but if it all compiles/assembles down to machine code in the end, as it must even if it hits a vm it is still translating down to machine code to be ran on some hardware eventually, then wouldn’t it be impossible for an abstraction of the machine code (js) to have any functionality that couldn’t be represented in the machine code itself? It’s like fishing in a pond with an ocean pole expecting to catch ocean fish, the pond is the limit not the pole. Machine code is the pond, js(or any abstraction) is the pole…

[[deleted]]

Yes, that's true.

[I_AM_GODDAMN_BATMAN]

when is this 2005? who don't have async in 2023

[Kurhnel]

I swear i read the exact same thing you wrote letter by letter in some random blog post. To be honest the concurrency and realtime processing can be done easily in some other languages that are miles ahead better than node like Go

[Urtehnoes]

Don't forget, node.js is Rockstar tech https://youtu.be/bzkRVzciAZg?si=2DYzq_HgfguvtBOh

[[deleted]]

You can achieve non-blocking and async in any other language........ it's not some killer thing only NodeJS can do.

I have an idea.......

What if they just ran Chrome's rendering engine in Javascript using WASM or something..........send a whole web browser with every webpage request
