Function

Use double quotes to contain the code.
Inside the double quotes, escape any double qutest with \"
so the code will look complex.
------------------------------------------------------------------
Function("((a,b,c,d,e,f,g,h)=>{console.log(\"eee\");})(\"aaa\",\"bbb\",\"ccc\")")();
------------------------------------------------------------------

This way, you cannot run the code immideately after
taking it out of Function(...)

Functionの内部にコードのサイズを伝える方法。

(function(v){
	(v.f=new Function("px",v.code=`

		console.log(px.code.length);

	`))(v);
})({});
