🤔 Can you guess what’s the result of "Hello, World".replace("","-")?

[karelpeeters]

I'll bait: H-e-l-l-o-,... you get the idea.

too lazy to try, did Karel win?

[karelpeeters]

Oh I was close, it also starts and ends with `-:-H-e-l-l-o- -W-o-r-l-d-!-`.

[enleur]

same with "Hello".split("")

[Ruckus]

How does "hello".split("") produce -H-e-l-l-o-,- -W-o-r-l-d-? 🧌

I knew kotlin wasnt yet ready for production

[enleur]

it produces list("", "H", "e", "l", "l", 'o", "")

[Ruckus]

I know, I was being facetious.

So an empty String in Kotlin with the split and replace functions covers every character in the String, very neat! 😄 Can see how that would come in handy with some situations.
