Solution for this Facebook post:

hi,i don't know how can i mask(change to star) a first all characters and hold last 3 characters, i don't want use for loop,have any idea is use replace to do that
for example:
123@email.com change to **********com
12345@email.com change to ************com
[...]

let email = ys@gmail.com;
let emailed = email..replace(/[^]/, '*');
but next, i don't know how can i do next step 😂
