Question

What is the most efficient way to empty an Array or Vector in ActionScript 3?

I’ve always just re-initialized them:

vector = new Vector.<T>();
array = [];

It doesn’t look like there’s an empty() function or anything similar.

Is there a better way?

Answer 1

Re-initializing the array is fine in most cases, since the garbage collector will just sweep up the old array. Still, if you want to empty an array without creating a new one you can set array.length = 0
