Reply To: is for loop better than for of ?

[Alexandra]

in the functions i have tried to put in instead of of

view.loadBlogPosts = function () {
    var posts = model.getPosts(),
        postsMarkup = document.createDocumentFragment(),
        primaryContentEl = helpers.getPageContentEl();
    for (var post in posts) {
        postsMarkup.appendChild(view.createPostMarkup(post));
    }
    primaryContentEl.appendChild(postsMarkup);
};

And it doesn’t work , title and content are displayed as undefined, why ?
