is there a command to empty or clear an array (list) immediately?

i see myArray.remove() / myArray.remove(i) but this seems to only remove one index at a time.

should be myArray.length = -1
it get complicated if you have more dimensions.

sure you can of course iterate to remove them 1 by 1 manually, but that will be slow as tar as it will have to perform a resize operation for every index

surely there is a way to just empty it in a single operation?

I'm curious to know if it actually frees up the memory from that array when you change its length, or if it merely flags those sectors as available and waits to overwrite them as needed?

Looks like it is freed. I ran a test with an array of 500k strings, checked memory use in sysinternals process explorer, reset the length and rechecked the memory, it dropped by half.

a property change is often similar a function that is called, it resize the array so i guess it also handle the allocated memory.
