Unexpected identifier in this line of code

I'm new to JQuery and trying to get this example going

https://github.com/tuupola/jquery_lazyload#readme

I downloaded the jquery library, added class ="lazy". But now, I added this line of code

$("body").append("<script>$("img.lazy").lazyload();</script>"); 

Select allOpen in new window

to a .js code that's already in the project but it throws an error : unexpected identifier

not sure why.

init: function() {
				// register initializations here
				
				// quick view dialog div
				jQuery("<div/>").attr("id", "QuickViewDialog").html(" ").appendTo(document.body);
				
				// bonus product dialog div
				jQuery("<div/>").attr("id", "BonusProductDialog").html(" ").appendTo(document.body);
				
				
				$("body").append("<script>$("img.lazy").lazyload();</script>"); 
	
				// micicart object initialization
				this.minicart.init();
				
				// execute unobtrusive js code
				this.execUjs();

Select allOpen in new window
