Is it possible to keep the remaining placeholder value visible when user is typing?

and as user starts typing the placeholder goes away

As ux point of view it is not very intuitive as users can forget about the pattern and then again they have to go back to see the format. It would be extremely usefuly if this feature is available.
While I agree with the usability side, it’s not a feature I’ve seen anywhere else.
It feels like it would battle for attention.
Maybe a “traditional” tooltip that shows up when the user starts typing, and goes away once the requirement is fulfilled?

Yes i can surely add tool-tip or label to avoid confusion but i really want to avoid any repetition. If you see jQuery Mask they add placeholder and its always visible https://github.com/RobinHerbots/Inputmask , but the issue is in this case the mask is quite prominent throughout which I do not need. Also if the placeholder text is significantly lighter compared to the actual typed text i do not think it would battle for attention as the difference will be quite obvious.
Having the possibility to make the placeholder always visible would be really great. Here is another example of project which provides this feature: https://github.com/santalu/maskara . I agree with @Tajwebdeveloper
Any updates on this feature?
@Tajwebdeveloper Why has this issue been closed?
