		Singleton that connects the engine with the browser's JavaScript context in HTML5 export.
	</brief_description>
	<description>
		The JavaScript singleton is implemented only in the HTML5 export. It's used to access the browser's JavaScript context. This allows interaction with embedding pages or calling third-party JavaScript APIs.
		[b]Note:[/b] This singleton can be disabled at build-time to improve security. By default, the JavaScript singleton is enabled. Official export templates also have the JavaScript singleton enabled. See [url=https://docs.godotengine.org/en/3.3/development/compiling/compiling_for_web.html]Compiling for the Web[/url] in the documentation for more information.
