JavaScript, the worst programming language on the planet

There are quite a few candidates for the worst programming language the Earth has ever seen. C++ is arguably software development schizophrenia. Java, its managed counterpart, with its rubbish exception handling, literally turns "encapsulation into an unproven theory". The average PHP file looks like something your cat sprinkled in its litter box in the morning after eating its breakfast. And Python on the other hand, is so slow you can literally eat breakfast yourself, while waiting for a loop to finish counting to 7. However, they're all bleak in comparison to JavaScript. JavaScript is the worst programming language on the planet, by far!

Don't get me wrong, there's a lot of great ideas in JavaScript. I love its dynamic nature. I adore its functional abilities. And since it's literally the only thing our browsers accepts, we're unfortunately stuck with it for the unforeseeable future. However, if you for some reason decide that you want to create your own programming language, do me a favour; Study JavaScript, and just make something completely opposite of it. Because that would literally create guarantees of that it would become a bajillion times better than JavaScript.

JavaScript is basically Lisp with brain damage

I once at replied Brendan Eich on Twitter saying he created JavaScript in 30 days. At which point he replied to correct me and said "11 days". I was tempted to reply; "That explains a lot of things". However, I kept my thoughts to myself ... ;)

In fact, the only positive thing I can say about JavaScript, is that it was better than VBScript, and that it was an open language, contrary to SilverLight and Adobe Flash. That's literally where my ability to speak nicely about JavaScript ends.

I don't mean to bash on Brendan. Brendan was one of the original heroes from the browser wars, and I personally know a lot of his colleagues, and he did great stuff with the allocated resources at his disposal back then. However, if you study JavaScript, please do not fall in love with it, because at the end of the day, its ability to allow declared variables to "fall through" scopes, its abilities to re-defined "this", and its lack of consistency on null/undefined/"God knows what", is the very definition of how to create a garbage programming language.

My partner sent me a link to somebody generating NodeJS code on the backend the other day. I think the idea was to show me a competitor to Aista. When I had explained a couple of things, his reaction was "Ahaa! ;)"

And no, I will not even link to them. Generating NodeJS code as an alternative to manually creating your HTTP REST API backend yourself, is basically the same as inventing a machine that spreads your cat's litter evenly applied to all walls in your living room. And I quite frankly don't want to have children believing that this is a sustainable way to generating backend APIs. If you want to play with a real programming language, that allows you to generate real backend APIs, you can find our stuff below. The reason why it's the only sustainable way to generating web APIs, is because unfortunately it's the only meta programming language in the world. Now you know ... ^_^

Because, have no doubt; JavaScript is the worst programming language on the planet!

I coded professionally with C++, ASP, Java, PHP, C#, JavaScript among others and also with C, Python etc for learning purposes.

I doubt you've any knowledge (beyond the surface at least) on any language mentioned in the post.
Just few concepts you repeatedly saw in programming humor websites or channels that you bring here with the expectation to find other people with the same source of truth and lack of experience applauding the text. "HAHAHA JS BAD".

Just quick sentences around: Java isn't the "managed counterpart" of C++, both are very different in every single detail (RE, compiler output, target etc etc etc).

JS was made in 11 days. When the aim of JS was to add a bit of interaction capabilities to the client side in websites. It's been a long journey of updates those near 30 years.

I coded a financial system tool for a specific niche on a company I worked in.
It took me 24 days and it had a revenue of >4m€. Now it has a revenue of >15m€ and it didn't happened just by existing. Many good devs keep working on that since the day I pushed it into production thus nobody can say "it was coded in 24days and it worths >15m€" without being completely wrong.

JS has become more convenient than other languages for several applications such high availability backend services thanks to it's async nature, also for anything that needs to be coded fast with low maintenance costs and it's that good in frontend that tones of people choose to use it to code mobile Apps and one of the best IDEs is coded with JavaScript. I'm talking about VSCode which is built with Electron.

I think that the evolution of JavaScript is one of the best things that occurred to the industry and still, that doesn't make other languages "bad". There are tones of languages out there and each one has a purpose and a target niche where it shines.

If I had to put a language (of the mainstream, widely used) as the worst one I'd choose PHP probably. And not for the lang itself but for the people maintaining it, it hasn't even lambdas in 2022. It's struggling to keep up with the industry demand since long time ago.

I would only disagree on PHP being the worst (heck, it kinda sorta does have lambdas these days). Though I do agree that the core devs are to blame for its sorry state. The language is in a phase where it can't decide whether it wants to be a significantly worse Java, or something actually useful.

From a language design point of view, I'd put groovy pretty high on the list of worst programming languages, because that's really a mess of trying to mix the best of four worlds without actually grasping any of them.

I'm not going to spend a lot of time arguing with you - However, as an interesting piece of fact, I think I'm quoted in the C++ std, and I (for sure) used to have an outbound link from Bjarne's homepage due to (his words); "having created a GUI library the way it should have been implemented by the std committee" ... ;)

It's been a long journey of updates those near 30 years

Two words; "backwards compatibility" ... ;)

I could probably debunk most of the other parts of your comment too - However, I don't have time since I'm going swimming with my wife, my son and his girlfriend ... :)

Then it's even worse.
If your "credentials" are what you say they are, you write controversial posts not by lack of knowledge but on purpose. It's quite sad because you could well get the respect of the community by sharing and teaching, instead you act like this kind of people that just want to watch the whole burn.

Despite that I put in doubt those anyway for the contradictions in your words from post to post and comment to comment. I'm not gonna judge your product because I've no interest in trying it but you look more like a salesman than an engineer.

As the CEO of a startup you have to be both? However, is there something wrong with being a salesman? And, do you honestly disagree with the premises of the article? A piece of advice, either keep on dodging my question, or take some time before you answer. I suspect if you answer before thinking, you’ll end up answering “sub optimal” … 😉

Yes and no repsectively, that doesn't mean you suddenly forget about one of both "roles".

I already answered in the comment above but if you want more:

if you for some reason decide that you want to create your own programming language, do me a favour; Study JavaScript, and just make something completely opposite of it. Because that would literally create guarantees of that it would become a bajillion times better than JavaScript.

Maybe you can inspire us by designing and publishing a language on your own.

The only issue JS has is retrocompatibility and any quirk can be extrapolated from this fact, on the rest is overall a first-class multiparadigm language. Do it needs a V2 and break the compatibility with the V1? Probably.

Can a generic polyfill tool solve the gap in between so we can start from a new checkpoint on JS's history? Probably as well. We're in the best time to think about this topics.

Retrocompatibility and evolution should happen in every language and piece of software, which is something difficult to handle and many decisions have to be made, some good, some not so good.

If you are going to create a new lang for any reason you'd do better checking JavaScript, at least the best parts of it and doing exactly the same.

If you don't like it it's OK, I'm not gonna judge your tastes 🤷🏻‍♀️

Alan Turing would object to that statement, considering it's Turing Complete and allows you to do most things other languages allows you to do ...

Paradoxically, it's almost consistently "old and outdated" languages, such as Lisp for instance. I've created a couple of languages myself; Lizzie being one. Not sure I'm 100% satisfied with it though. However, today I almost exclusively write in Hyperlambda (our own language), C# when I have to (to extend Hyperlambda), and TypeScript. TypeScript and C# is mostly because I "have to" though, and I tend to use both languages more in a functional style than its pure OO way ...

I like the "purity" of lisp but I find JavaScript used in FP style much more readable.

And don't you have the same discontent to c# than you have to java ?

Thread Thread
 
polterguy profile image
Thomas Hansen

JavaScript can be used in a great way, you just have to amputate most of its OO rubbish first, in addition to 90% of its other parts ofc. C# have the same trait, and most of the new ideas added to it the last decade have been functional constructs. It's almost possible to write entirely "functional code" using C# today in fact, in addition to that its runtime has evolved to become an amazing stack since .Net Core.

However, I really don't know to be honest with you, and I'm not sure if I truly like any of the so-called "modern and popular programming languages" most people have heard of today. At the end of the day, I'm mostly writing these articles to make people stop and think really. If I'm right in everything I say is actually less important to me ... :/

Like you said; "Sometimes it's important to stop and step back a bit to look at things neutrally". Our profession is filled with a myth, which is that "IT is developing so fast". For anybody having been around, watching C# spending almost 2 decades before being able to catch up with 50% of Lisp, that was created in the late 1950s, such ideas are troublesome. Joel Spolsky wrote a great blog about it two decades ago, it was called "Fire and Motion" - You should read it. It kind of explains my motives to some extent ...

As to Polish notation in Lisp - Yup, hate it! :/

Have you tried reverse polish notation (postscript for example) ? Same sh** without a Lot of Insane and Stupid Parenthesis (LISP) 😁

Hehehe, Lizzie that I linked to in one of my previous comments is not using Polish notation. Besides from that, it's basically a "super stripped version of Lisp" (no macros, and none of the really fancy stuff, but fundamentally "the core" from Lisp). However, I'm really into meta programming these days, which reduces the candidates down to one; Hyperlambda (another one of my languages) ...

Dude!

Asp.net was created on an airplane by Scott Guthrie.

Apple started on a garage.

Microsoft as well inside a garage.

Great things started small...

Yes it is messy! But it is definitely not the worst at all! The only goal of a programming language is to develop stuff and we have billions of apps being developed in JS right now.

Remember that "Software ate the world, the web ate software, and JavaScript ate the web." source

I don't disagree, and JavaScript has a lot of nice things going for it. However, if we believe things are perfect there is no room for improvement. A lot of kids learning to create software today believe things are perfect as is; OO, JS, you name it. I'm just there to remind them it's not ... ;)

I've got 40K readers per week now at DEV. Up from 10K a month ago, and we're getting 300 to 600 unique users on our website per day. So yes, it is working. In fact, I wouldn't be surprised if I'm the "fastest growing author on the platform, like ever, throughout its history", arguably adding equally much value to DEV as a company, existing in symbiosis with those getting paid to actually be here.

This technique is often referred to as "aggressive marketing strategies", and it's been applied by thousands of companies before me. However, me actually admitting that, arguably makes me more honest than most others having applied it earlier. When that's said, I agree 90% with all of my writings, and the parts I don't agree with, have moral justifications in that they force people to think - Including you may I add ... ;)

Psst, thinking is a GOOD thing ... ^_^

As to why I'm applying it, I have answered that several times before, and my answer is (still) as follows; "Unfortunately the world has grown so shallow that unless you've got boobs, or create cognitive dissonance, resulting in that all those disagreeing ends up commenting, attracting more readers to your OP, you're basically 'automatically uninteresting' - I have no boobs, so here we are" ...

Psst ... ^_^

This just now

This just now ^_^

If I'd guess, I'd say 98% of it is due to my "controversial brutal honesty based articles" here - Which doesn't invalidate a single one of my points may I add ;)

Anymore questions ...?
