AS3 Best way to clear an array

[gibsy]

What is the best way to clear an array? (performance and resources)

array.length = 0;

array = [];

array.splice(0);

[kglad · Accepted solution]

array.length=0;

If i use something like this:

arr = new Array();

some code

.

.

.

arr = new Array()

The variable arr won't be replaced faster in the memory with this new one?

that's creating a new array which is extra work, and it's adding an array to the objects that flash will gc, and that's extra work.

assigning the length to 0 is the most efficient way to clear an array.
