“Typed language? Yeah, I’m using a keyboard.”
I am currently teaching python and JavaScript devs Typescript. Everytime they hit a problem they switch to any
Sigh
Must be the same people who just comment out failing unit tests.
“Your crappy tests are failing again on my branch. I’ve commented them out until you fix them.”
Sadly that sort of thing got so common where I work that I’ll run the tests three times before considering looking into the error message to see if it is something I broke.
From time to time we take some days just to fix tests with inconsistent results, but there’s always more popping up.
Yeah, we have a team whose job is to make sure all our tests run well and fixing them if they don’t
Serious answer: You can’t write tests for untestable code. Your code needs to be pure if you want reliable tests: https://en.m.wikipedia.org/wiki/Pure_function
For integration tests, they should handle retries themselves
That’s why I kinda don’t like Python and JavaScript anymore. Every time I want types for a library it’s gonna take me time to get it working. For every serious project I do, I use a strongly typed language.
Just create a al Inter rule that rejects Any types and a pre-commit hook that refuses the commit if the linter fails. Sometimes the brute force approach is the best way to teach
the beatings will continue until typing improves
Eslint is your friend :)
I am happy there is no obvious “any” type in Rust.
Yeah, at some point my new team switched off null safety, because some consultants told them to.
Ride into the Danger Zone …
Indeed, and just as my old team fell for consultants, my new team also went ahead and let them add some overcomplex garbage into their codebases. And crap still keeps piling up. It’s just like it’s impossible for them to understand that from an average consultants perspective the only way to go forward is to keep adding complexity, wether they are aware of it or not.
Oh, the consultants know, but they get paid, don’t complain about “risks” and “code debt”, and management only sees their delivery on time without increasing operation costs
Well, you can always just add the type definitions later on.
I did port some C code to D, by just pasting it in a D file, then fixing the differences (changing type names, rewriting precompiler macros with D metaprogramming and inline functions, etc.).
i like when my strongly typed language can type itself, why should i have to type extra words because the compiler is stupid?
So that next time your coworker uses the wrong type, the compiler can scream at him: “NO I WONT COMPILE THIS YOU DUMBASS, LOOK JOHN SAID ON LINE 863 THAT IT SHOULD BE A DOUBLE, NOT A FLOAT FOR FUCK SAKE”
you can still have that without having to declare the type manually. check out Swift or OCaml for example
Tell me you are a Java dev without telling me you are a a Java dev 😂
As a JS dev, I can only wish we had those types 🥲

Type error unless there’s an implementation of
+that specifies adding together and integer and a string.💯% accurate. funny how the typescript developer thinks this is some kind of “gotcha!”… like maybe just try a language besides typescript and find out for yourself 😆

my complaint is that typescript is stupid, yes. so why wouldn’t i compare to what other languages do that is less stupid?
on the plus side, at least now i know that the ad-hominem minded devs came here too, and brought their righteousness with them.

“brought” 😏
Exactly. Most languages I know of that allow this at all will coerce the “1” to an integer and give x = 2. They get away with this because they define the “+” operator as taking numbers only as arguments, so if you hand them
x = x + "cheese"they’ll error out.OCaml 😍
Does it compile???
… Compile???
typescript is not a strongly typed language
I mean that is the first step. ¯_(ツ)_/¯ The next step is to start defining the types more strictly than any.
I’m in this post and I don’t like it.
That being said I try to have specific types in my typescript but coming from working without typescript, there’s so much more words involved using typescript and for what I use it for I don’t really see the use case. Sure it helps you realize what part of the script needs what data types but it adds so much more complexity in the code that I’m not really sure it’s worth in the first place.
Typescript saves ridiculous amounts of time in bugfixes and is IMO a lot more readable than JS.
I don’t know how many times TS has complained about some type mismatch in my code that made me scratch my head for 2 seconds to only then realize I was doing something stupid. With plain JS that would’ve been no issue, until I have some obscure bug 30 minutes later and have to figure out it’s source.
Also, whatever piece of code you are working on, to do anything you have to have the types of your variables/functions in mind. If you have to keep track of all of them in your head, you will definitely mess it up at some point or have to look through a bunch of different methods/files to track down the source of some piece of data to be certain what’s contained in it.
So yeah, TS might take slightly longer to type out, but it saves you a lot of dev time.
I mean I guess that could be helpful, I’ve never really had that issue so I have yet to see the benefit of it. I just find it useless work that you’re typing out for something that the engine itself isn’t going to be able to see anyway, which means you’re going to have to have unit tests coded in regardless. And I wouldn’t say just a little more coding, typescript when implemented into my project doubled the amount of code provided, I’m trying to use it because I do understand it’s a standard, but I really don’t understand why it’s a universal standard, considering that everything it does is completely syntax sugar/coder side and it doesn’t actually interact with the underlying engine. I feel the same way about coffee script honestly.
Just wait until you have to work as part of a team on a big project. The lack of types will murder the team’s productivity
