WebbTo the Ruby interpreter, it’s pointless to evaluate the second half as the overall expression can never return true. With the operator, if the first expression evaluates to true, then the second expression is never checked because the complete expression is already true, and the code in the block is run. In any programming language that implements short-circuit evaluation, the expression x and y is equivalent to the conditional expression if x then y else x, and the expression x or y is equivalent to if x then x else y. In either case, x is only evaluated once. The generalized definition above accommodates loosely typed languages that have more than the two truth-values True and False, where short-circuit operators may return the last evaluated sube…
