4:30 - Haha... Your videos are SO interactive!! I was just about to ask this question in comments. Before I've seen your explanation I paused the video and played with Math.ceil() in the VSC - couldn't get 0 in practice but I figured that theoretically it's possible. And here you go confirming my thoughts. Just amazing! :))

// outputs 43?
I was expecting NaN? as 43 is a string here?

Why do we say that random numbers from 1 to 10?Because we also get number 0.Then should we call it random numbers from 0 to 10?I confuse my brain maybe, but it made me think a lot)

[GoGetSP]

console.log(Number.isNaN(0 / 0)); //outputs true??
//outputs false??

[GoGetSP]

I was playing around with Math.min and Math.max functions and came across
console.log(Math.min()); //infinity
console.log(Math.max()); //-infinity

I have been trying to understand it through various blogs but couldn't.

Please somebody explain.
Thankyou!

Hello, sorry, but I did not understand properly why Math.ceil is not a good way while generating random numbers?
