Is it better to declare variables at the start of a proc, or closer to where
needed?
Thinking about loops
proc testProc() =
for i in 0..100:
var j = ""
j = $i
Run
There is overhead to create and destroy a variable 100 times. Yet, program best
practices are to keep variable declarations near the location of use, as
practical. Usually I declare at the top, but sometimes declare inside a loop.
While cleaning up old code I came across this and realized I had no rationale
reason for doing it one way or another.
