my bad(

But description clearly says what to do when some value is out of 0-255 range.

.

Any values that fall out of that range must be rounded to the closest valid value.

There is no issue.

It has bugs, because of given sample
expect(rgb(255, 255, 255), equals('FFFFFF'));
expect(rgb(255, 255, 300), equals('FFFFFF'));
expect(rgb(0, 0, 0), equals('000000'));
expect(rgb(148, 0, 211), equals('9400D3'));
expect(rgb(148, -20, 211), equals('9400D3'));
expect(rgb(144, 195, 212), equals('90C3D4'));
expect(rgb(212, 53, 12), equals('D4350C')); using dart language

way too easy for 5kyu tbh

const marioAdapter = new MarioAdapter();
const target = {health: 22};
Test.expectError('should adapt mario', () => marioAdapter.attack(target));

It's not clear what's being tested from such error message.

You're not supposed to create an instance of Mario when no argument is provided.

do you think that i dont know markdown ?
how do you think i added screenshot to the comment ?

its not my problem that codewars cant default sreenshot size

What are you doing man? Seems like you hacked the site. There's no room left on the page. Please give a link rather than do that. Or better, learn to copy and format code cleanly: https://docs.codewars.com/references/markdown/#code-block

The user's already solved the kata.

When you got the joke it should be accessible through a simple API of saySetup and sayPunchLine methods.
