how works dataLength ?, different result when is a static number

[kypanz]

Hello i am curious about how this works, let me explain

if i put in dataLength for example : arrExample.length works fine, but if i put a number , for example 20 , 1 or anothers, this only render one time ? , why this happend ?

the documentation says : set the length of the data.This will unlock the subsequent calls to next.

i am not sure but i have my theory, in this case the arrExample.length works fine beacuse every time is called the next function is re-rendered with a new value, for example if arrExample.length = 20 in the first render and in the second has 40 has value this means this only need a different number every time has re-rendered and not care if it is a any number, i only courious about this

i am right ?, how works internally ? , please if i am wrong let me know i wanna know why this happend

thanks for read and have a nice day ❤️

I think that's what it looks like, but no one explains it.
