try type to your console this code: "typeof NaN"

Thank you very much for your feedback, it is valuable to me! I have a few ready-made ideas on the topic of information security in stock, so look forward to it soon)

Nice hack. Now fixed

Yes, I thought there were similar tricks that I missed. Now the hack you provided doesn't work.

Thank you so much for the fixes!!!

I have not seen before this kata, the link to which you gave. Besides, I wouldn't say it's a duplicate.

In the kata you have given, the researcher has a specific starting point. In my kata, there is a certain closed system that you need to play with in order to identify a vulnerability, and then you need to come up with / implement an algorithm that exploits the vulnerability found. The value of my kata lies precisely in the research that needs to be done.

I look forward to feedback.

Also, if you write briefly about the course of your thoughts during hacking, how you came to a decision, criticism and emotions that you experienced during this, it will be very important to me. It takes a lot of time to create, test and analyze a kata, and it's hard for me to do it without realizing that I'm doing something right. Thank you!

Try:

console.log(zero(';console.log("hello from rce!")'))

Thanks for noticing. The problem really was also in the main tests. Solved.

How do you like the kata in general?

Looking forward to the next one

Here's the next one. It's similar but harder:

Thanks, good idea. Added.

Can you give more detailed feedback on kata?

Removed. But tell me what exactly this inscription at the very end of the description interferes with the passage of the kata?
