Default why are there holes in electric plug prongs?

Not technically a home repair topic, but:

Do the holes in the prongs of an electric plug serve any purpose? If
so, what is that purpose?
Thanks for any information.

Hi,
When you plug it in it mates with dimpled tab to make secure contacts.
If in double break apart a receptacle(only couple dollars a piece) and
see for yourself.
