what the difference between rewrite variable or declare new variable in a loop

Hello dear community a have a question. If I declare a variable in the head of a script and overwrite them value in functions like "_process" for example. Is it better for optimization than declaring a variable in the body of functions?

Hi,

Probably from performance point of view overwriting could be better, but I'm not sure if that is worth it in this case. In most cases you probably won't see any difference.

Local variables are typically stored on the stack, so creating them is not as costly as dynamic allocation in heap.
