No sense to include another library just to change the syntax a little bit
$("<p>",{"class":"gretting",html:"Hellow World"}).appendTo("#helloWorld .output")
And you can also create hierarchy $("<p>",{"class":"gretting",html:
$("<a>",{href:"#",html:
$("<h1>",{html:"Hello World"})
})
}).appendTo("body")
Which looks disgusting but that is why template engines exist.
