-				Creates a typed array from the [param base] array.
+				Creates a typed array from the [param base] array. All arguments are required.
+				- [param type] is the built-in type as a [enum Variant.Type] constant, for example [constant TYPE_INT].
+				- [param class_name] is the [b]native[/b] class name, for example [Node]. If [param type] is not [constant TYPE_OBJECT], must be an empty string.
+				- [param script] is the associated script. Must be a [Script] instance or [code]null[/code].
+				Examples:
+				[codeblock]
+				class_name MyNode
+				extends Node
+
+				class MyClass:
+				    pass
+
+				func _ready():
+				    var a = Array([], TYPE_INT, &amp;"", null) # Array[int]
+				    var b = Array([], TYPE_OBJECT, &amp;"Node", null) # Array[Node]
+				    var c = Array([], TYPE_OBJECT, &amp;"Node", MyNode) # Array[MyNode]
+				    var d = Array([], TYPE_OBJECT, &amp;"RefCounted", MyClass) # Array[MyClass]
+				[/codeblock]
+				[b]Note:[/b] This constructor can be useful if you want to create a typed array on the fly, but you are not required to use it. In GDScript you can use a temporary variable with the static type you need and then pass it:
+				[codeblock]
+				func _ready():
+				    var a: Array[int] = []
+				    some_func(a)
+				[/codeblock]
