Javascript Object instantiated inside its declaration
This pattern makes sure that whether you call circularBuffer with new or not, you still get a new instance. So both of the following result in a new circularBuffer instance being assigned to cb: var cb = new circularBuffer(100); var cb = circularBuffer(100); In the first case, this is a circularBuffer instance so it follows the if path. In the second case, this is window so the method follow

Prolog - Arguments are not sufficiently instantiated - Knight/chessboard
It's breaking on the >= test in validSquare. You can't determine the truth value of X <= Y when both are unbound, basically, because numerical operators don't assign values. You could solve this by using a member to bind the coordinates to valid squares, i.e. validSquare(X1/Y1, X2/Y2):- member(X1, [1,2,3,4,5,6,7,8]), member(X2, [1,2,3,4,5,6,7,8]), member(Y1, [1,2,3,4,5,6,7,8]),
