why the value of 0! is 1 ???

As n! Can also be expressed as n×(n-1)!
So if we take 1!=1 (1-1)!
it simplifies to 1!=1×0!
there are more ways to prove that as well...

Yeah it kind of goes along with the pattern of factorials, so it's nice to have it defined as 1.
I think they mentioned that in this vid too: https://www.youtube.com/watch?v=Mfk_L4Nx2ZI
