		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.

				Execute the string [code]code[/code] as JavaScript code within the browser window. This is a call to the actual global JavaScript function [code]eval()[/code].
				If [code]use_global_execution_context[/code] is [code]true[/code], the code will be evaluated in the global execution context. Otherwise, it is evaluated in the execution context of a function within the engine's runtime environment.
