If the Kata supplied floats, then this would have been invalid. But it doesn't.

readibility left the chat.

to be fair, you are doing the same by using .toCharArray and .length

that is, if 2.5 or 6.5 days, does the discount work?

гениально

Same here, I either didn't know or forgot that I can use two ternary operators in one line.

Entendi que neste caso o employed não precisa ser true para a condição do exercicio ser satisfeita, me corrija.

I like how simple this is.
As a beginner i'm still writing out the long version and explicitly declaring statements, so this is very useful to see the shorthand versions of the same thing.

note for my benefit:
learnings from yours:

1. brackets not necessary for simple conditional test.
2. '!' operator understood as 'not true' is the same as '=== false'.

Nicely done man. I was getting too clever for my own good and this was a good ego check.

Nice job with regex

why not? it's easy to read

Самое лучшее решение. Коротко и лаконично! Супер

I am super noob, but ternary looks good only with 2 conditions. I would rather have more rows than a line so long

A very commmon eslint rule is no nested ternary. This would not fly in many teams.
