4,393 PointsDeclaring variable outside of the function
Can I render the items variable outside of the function? I've tried it myself. The result looks the same. Wonder what's the different having the item inside/outside the function. Thanks!

231,269 PointsThe function will perform exactly the same if items is created in the global space, but since it is only used inside the function it is better practice to create it there. That way, after the function is finished, that variable can be disposed by the system and the space reclaimed instead of it continuing to take up space and not be used.
