	<brief_description>
		A wrapper class for native JavaScript objects.
	</brief_description>
	<description>
		JavaScriptObject is used to interact with JavaScript objects retrieved or created via [method JavaScript.get_interface], [method JavaScript.create_object], or [method JavaScript.create_callback].
		Example:
		[codeblock]
		extends Node

		var _my_js_callback = JavaScript.create_callback(self, "myCallback") # This reference must be kept
		var console = JavaScript.get_interface("console")

		func _init():
		    var buf = JavaScript.create_object("ArrayBuffer", 10) # new ArrayBuffer(10)
		    print(buf) # prints [JavaScriptObject:OBJECT_ID]
		    var uint8arr = JavaScript.create_object("Uint8Array", buf) # new Uint8Array(buf)
		    uint8arr[1] = 255
		    prints(uint8arr[1], uint8arr.byteLength) # prints 255 10
		    console.log(uint8arr) # prints in browser console "Uint8Array(10) [ 0, 255, 0, 0, 0, 0, 0, 0, 0, 0 ]"

		    # Equivalent of JavaScript: Array.from(uint8arr).forEach(myCallback)
		    JavaScript.get_interface("Array").from(uint8arr).forEach(_my_js_callback)

		func myCallback(args):
		    # Will be called with the parameters passed to the "forEach" callback
		    # [0, 0, [JavaScriptObject:1173]]
		    # [255, 1, [JavaScriptObject:1173]]
		    # ...
		    # [0, 9, [JavaScriptObject:1180]]
		    print(args)
		[/codeblock]
		Note: Only available in the "HTML5" platform.
