re: No matter how clean code you write, once you reach certain threshold you'll run into problems with JavaScript. There is a good reason why it's one ...
 

Nikola, my friend...

It's not right to assume that there is some "threshold" without having a solid proof (aka running into one).

Cuz really, tons of companies are doing just fine with the normal JS... not just fine, but actually PERFECTLY FINE.

Even us (Coretabs Academy), we are doing really great with the normal JS, and we super barely have problems.

I mean, before throwing such assumptions about "long-run" and "large codebase", please try it and see how it goes.

Hey Yaser,

I don't know why you think I'm just assuming it - I actually have experience working with a bigger code base written in JavaScript and TypeScript (our front-end part is written in JavaScript, and back-end is in TypeScript).

I doubt anyone can give a specific proof for this and we can all talk from our experiences. As I answered before, this is my experienced combined with the stories I have read on this topic (dynamic vs static / strong typed systems) written by more experienced software engineers and I'm definitely not saying this is something written in rock and I would like to see examples where this is not true.

Right now I'm working on an e-commerce system written in TypeScript. I don't know how much lines of code it has nor I think it's important here. What I can say for sure is that it makes me much more productive to know upfront if there is some potential problem with my code instead of running into problems in runtime. Time which I would have to spend debugging the problem may not be high, but it adds pretty quickly. At the start it took me more time to properly structure my code, but in the long run, I believe I saved much of my time.

I'm not saying that just using JavaScript will bring you the problem - what I'm saying is that bigger, properly structured TypeScript code base will prevent you from running into the problems which could happen to you more often with the same code base written in JavaScript.

As I said before, writing in strong / static typed language is not a substitute for the proper structuring of your code base, but my personal experience is that it's much more productive to write and manage huge code bases in TypeScript than in the JavaScript. If you think otherwise, I would like to hear your experiences on this topic too.

we super barely have problems.

This is from your site.

If members had type Member[]? this would have been caught by typescript, and you'd be forced to check whether it was defined.

It only took me a minute on your site to find that, what else do you suppose is lurking in there that could've easily been caught pre-runtime?

Thanks Nikola for sharing your view, I really understand what you're saying.

My point of view about TS is that it adds extra code... and from my experience: extra code = more work and more time consumed (no matter how it is).

I always see the LOC as a liability, not an asset.

I don't know why you think I'm just assuming it - I actually have experience working with a bigger code base written in JavaScript and TypeScript

I saw your GitHub has 17 contributions in the last year (and mostly on non JS code), it's something you might want to change... cuz people do judge on that (sorry for judging too fast).

I'm not saying that just using JavaScript will bring you the problem

You just laid your hands on the blind spot that I saw in this whole discussion (from other devs in this topic).

Which is (dynamic vs static) typing langs will solve the problem, it's not.

I believe the whole discussion should be about the architectural & design decisions and the developer expertise.

Yes, you're absolutely right about how TS introduces better design decisions.

I faced exactly the same experience when using C# then Python. I said C# (and ASP Core) tells you exactly how to do things, but Python gives you all the flexibility and power to do things in anyway.

In time, I realized that I finish my projects in Python on time much more faster that what I did on C#!

Why? cuz I transferred that knowledge (of doing things the right way) from C# into a language that allows me to do me doing things in anyway.

And that is ultimate power, and the only catch is as you know:

With great power, comes great responsibility

@maxinertia

This is from your site.

Does that affect the end-user in any way (would he see any unexpected result)? NO

Then, do I care? NO

Yaser,

Just because something doesn't affect the user now, doesn't mean it won't affect it later or cause another, seemingly unrelated error.

That was hilarious, you caught him off guard with that bug.

“It only took me a minute on your site to find that, what else do you suppose is lurking in there that could've easily been caught pre-runtime?”

Hahahahahahaha hahahaha hahaha 😂 these fools with their “TypeScript is not helpful” crap. 💩I can just imagine how hard it would be to understand their codebase.
