What is short-circuit evaluation in loops?
It is an optimization where the computer stops evaluating a multi-part boolean condition (using && or ||) as soon as the final True/False result is mathematically guaranteed.

The loop condition is evaluated at the start of the loop and before every subsequent iteration. If it runs 100 times, the condition is evaluated 101 times.
Because the function will be executed on every single iteration. If the function is slow or computationally heavy, it ruins the algorithm's performance.
Caching means storing the result of an operation (like an array length or function return) in a variable outside the loop, so it only has to be calculated once.
