It's now the third most answered challenge!

Here comes the 300. Changed to 2407 bytes though.

Q: Feedback for an addition to the snippet that tells you whether a language is able to be used?

user71546

I think that's a good idea, but if the language is hand-typed (not auto-generated by TIO etc) then the detection may become more difficult.

NieDzejkob

I think it's better to have fuzzy-matching instead of .startsWith

Yay

Mr. Xcoder

I can't wait to solve an easy sequence in triangularity :)

caird coinheringaahing

I'm quite glad that it was @user71546 first answer to the challenge. Makes it seems less of a niche question

@Mr.Xcoder You have exactly 50 challenges tagged with code-golf (tips don't count) :P

Mr. Xcoder

@cairdcoinheringaahing Really? Nice :)

Thanks, good to know

NieDzejkob

almost done with next sequence in trefunge :)

caird coinheringaahing

Of all the languages you could use (literally all of them), you choose trefunge?

NieDzejkob

13:54

yup

Mr. Xcoder

Yeah ಠ_ಠ Trefunge

caird coinheringaahing

@Mr.Xcoder We could try it in Jelly? Let Nie post his though

I wonder how long it will take for the feed to react...

caird coinheringaahing

My phone just buzzed. I knew what it was without checking it :P

It is taking a while...

here it is...

it took 18 minutes, but it worked

user71546

@cairdcoinheringaahing well the 2nd indeed, #297 is also mine.

caird coinheringaahing

@user71546 Ah, didn't notice that :P
