First take expression in innermost parentes:
1.
1 || 0
operator || returns true if either one of two is true, otherwise false, so result is true (1)
2.
second parentes
1 && 0
operator && returns true if both true, otherwise false, so result is false (0)
3.
!0
operator ! is reversing (true is false, false is true), so result is true (1)
