It's a lambda expression! Sort of like a simplified method. In this case, you can think of the => as a kind of return statement.

What does the => do?

Nice one

wait, are you invoking a function within itself? How does it work?

P.S. I'm new don't kill me ;-;

I have seen something like this, but you made it in the single line of code. Amazing

Help us help you.

Specify what language you're having this problem with. Probably add your code, marked up and spoilered.

Closing.

Same problem for me

All basic tests passed, but the random one fails everytime :-/

testSortItOut_random(KataTest)
arrays first differed at element [4]; expected:<30.7> but was:<33.4>

Thanks :)

You sir :) you've earned my respect

Same here ^^...
