A short-circuit evaluation is where each part of an expression is evaluated only as far as necessary to determine whether the entire expression is true or false.

In short-circuit evaluation, if the first operand in a logical AND (&&) operation evaluates to false, the second operand is not evaluated, because the whole expression cannot be true. Similarly, in a logical OR (||) operation, if the first operand evaluates to true, the second operand is not evaluated, because the whole expression is already true. This optimization technique avoids unnecessary evaluations.
