perfectly

I mean it is simple and clever, but in a big teams sometimes happens that other coders could read such short expressins wrong. misunderstanding. for example here if you use parseInt(inputString[0]) it would be more visual recognisable according to task discription.

Apologies, but can you please explain what is difficult to understand?

Very clever, but such disisions are difficult for understanding by others if you work in a big team...human factor is coming)

Excellent !

that is all there is!!

good one

I love short code <3

I believe this is fixed now.

That's brilliant!!

I literally smiled after understanding how this works. thank you!

My guess would be that filter creates a new array and populates it, while reduce just generates a single number.

It's converting the mean into an index for the string.

In C, a string is null-terminated by definition. All string.h functions assume this. If you pass garbage to strlen() then it will spin through memory until it finds a '\0' or generates a segmentation fault.
