What is short-circuit evaluation in programming?
Short-circuit evaluation is a programming technique where the second argument is evaluated only if the first argument is true.
Can you give me an example of how it works?
Sure! In an expression like A && B
, if A
is false, B
is not evaluated because the whole expression can't be true.
What about with the OR operator?
With A || B
, if A
is true, B
is not evaluated since the expression is already true.
Are there any performance benefits to using it?
Yes, it can improve performance by avoiding unnecessary evaluations, especially in complex conditions.
