Godot - Set array size

GDScript code example to set array size.

Can set array size using resize() in GDScript.
Added values will be set to "null".
Also resolves errors like "Invalid set index '0' (on base: 'Array')" when adding value to empty array.

var array = []
array.resize(5)

print(array)
# [<null>, <null>, <null>, <null>, <null>]

If resize() is set to lower number than values that already exist in array, values are truncated from beginning of array.

var array = ["apple", "lemon", "apple", "banana"]
array.resize(2)

print(array)
# ["apple", "lemon"]
