    If you’d rather not play around with all that messy string concatenation when performing costly DOM manipulations, give createDocumentFragment a try.

    var div = document.createElement(“div”);
    div.appendChild( document.createTextNode(“Test div to be inserted 100 times”) );

    var fragment = document.createDocumentFragment();

    for(i = 0; i < 100; i++) { fragment.appendChild( div.cloneNode(true) );

    document.getElementById(“container”).appendChild( fragment.cloneNode(true)

    Amazingly the browser support for documentFragments goes back to IE6.The benefit comes from the ability to add the entire fragment DOM tree into the page DOM with one insertion – just like the method outlined in the article.
