Regular expressions about /(?=\D*\d)/

[RaymondGuo]

Should the code following be changed
from
" /(?=\w{3,6})(?=\D*\d)/"
to
" /(?=\w{3,6})(?=\d{1,})/"?
It really took me much time to understand the first line until I wrote down the second line, but I’m not sure if it is OK.
And another choice is
from
" /(?=\w{3,6})(?=\D*\d)/"
to
" /(?=\w{3,6})(?=\d\D*)/"?

Both of the choices I wrote are better understood, am I right? Anybody can help me confirm that? Thanks.

Your code so far

let password = "abc123";
let checkPass = /(?=\w{3,6})(?=\D*\d)/;
checkPass.test(password);
