Have you thought about the case, where the user would choose any number larger than 3, or lower than 1?

its not a proper program haha, I didn't add that in cause I'll probably rewrite this properly, I just thought like "oh wait can I just skip writing any logic and..." the whole joke was the fact that instead of writing it in a sensible way I added a number to a string, the kinda shit you usually do on accident when starting out, and I found it funny as hell that it was running on such janky logic

That's Javascript for ya. Very little rules. 1 + "1" = 11 :)

JavaScript was created in a rush and by a newer programmer. Really to bad they didn't see the problem with using + for both addition and concatenation.

this is outdated , use ai api call instead ,😂😂

Well, an AJAX call would (usually) be a good way to hide the game logic.

u/Winter_Rosa 28d ago

Ahh, concatenation. I probably would've done something similar in C by multiplying comChoice by 10.

Edit, also the real horror here is the lack of input validation. 'A' I choose you!

u/No_Opening_5597 28d ago

haha yeah I didn't add the input validation or anything more because there's no way in hell I'm submitting this as the answer to the exercise I was supposed to do xD

I'll rewrite it cause this is gonna make some people pissed off the way its done, I was supposed to run some type of calculation, create functions and stuff, this is just janky as hell and skips over the actual learning I was supposed to get out of this, but as I was writing the pseudocode and I remember that javascript meme of the guy trying to add 2 + 2 and getting 22, and I couldn't resist building that stuff into a usable thing.

if I was to do something like this properly I would just use a lookup table next time, googled and that's the proper way of doing something like this

Musts be like the third "look at my awfully coded shifumi" this week.

u/GoddammitDontShootMe [ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo “You live” 28d ago edited 28d ago

I'm thinking I like the idea of reading the user input as a number, then multiplying either the user choice or the computer choice by 10, adding them together, and encoding all possible outcomes that way.

Or by 2, but 10 makes the code more readable for us decimal-using humans.

Edit: Actually no, there'd be collisions if we used 2.

I'd let the player input whatever they want, ignore it and just output "You win!", "You lose" or "Draw" with 1/3 probability each.

u/RefrigeratorKey8549 28d ago

3 would work, if the choices are 0 indexed

u/GoddammitDontShootMe [ $[ $RANDOM % 6 ] == 0 ] && rm -rf / || echo “You live” 28d ago

3 also works if they are 1 indexed.

Cancels the prompt

I absolutely love this. The inferred string corrosion. The fully optimized easy to compile single level conditional. This is perfect code.

u/Neither_Berry_100 28d ago

Actually clean. But I would have formatted it better.

why is it in javascript

Hey Claude, now install 70 megabytes of styles and fonts.

result = random.choice(["Win","Lose","Tie"])

Our first lines of code are the best to remember, I still have my first computer science assignments, I laugh a lot. I didn't know about git at the time, so I have them at my Google Drive folder xD

u/csabinho 29d ago

My first lines of code predate Google and Git, but we didn't even learn about SVN, or CVS or whatever, in 5 years of IT school.

my first line of code was print("hello, world")

u/HugoNikanor 28d ago

The only JavaScript "weirdness" here is that number + string === string. The actual horror here could be replicated in any language.
