Last night, I was scrolling through twitter and I found a interesting JavaScript question, and I bet you won't be able to answer this without cheat...

I wanted to see if ChatGPT will get it right.. And it did :)
The NaN part is very interesting, as one of the "a" chars is dropped, initially, I didn't understand why it's not "bananaa" (extra "a"), now I get it 💪🏻
banana
What!! No wayy, how is it banana
Where does the n come from??
Unary plus on "a" gives you
NaNNow try
console.log(new Array(4).join(Number('y tho') + 'a')+' Batman!')🦇NaNaNaNaNaNa batman!is that the desired output or am I missing something? 🤔Yes, maybe for people from my generation 😅.
Now I think this joke is too old 👴
Haha, maybe that joke is from the 'dad joke' era! 😄😄.
NaN is actually part of IEEE 754, which is used in most languages to express floating point numbers.
Its actually banana, basically the unary plus(++) of 'a' gives NaN which gives us 'baNaNa' and convert it to lowercase => banana
Do you need
at the top of the script 🤔
I used an online Javascript console.
Try this code :
Thank you; my mistake.
I didn't see the ++.
For my defence on my phone it red:
yep, that' s what it does.
Okay the person who thought of this problem is soooo clever
JavaScript is really a magical language
when it gets to insane questions...
That's honestly cool.
and weird
Is it bAaa
It's the little things that makes javascirpt so annoying :)
In your case it's bananaa
It's
banana✅✅
now i see why typeScript and them exist.
obviously it is string :"b"+string :"a"+NaN+string :"a".
Do not ask me about the last string :"a".
let us say it is your homework.
banana
It took me a second because I didn't notice the ++ (Unary plus) right away. Definitely got a little laugh out of me once I caught it though.
