Add a couple of great examples

Pick a couple of examples and link to them on gh-pages.

+1. Love the library btw.

Backbone view render example would be appreciated :)

Does anyone have any great examples of problematic Layout Thrashing in a real project, which Fastdom clearly helps to solve? If we could demonstrate a before/after along the lines of http://wilsonpage.github.io/fastdom/examples/animation.html with a real project, that would be an awesome introduction to how simple and powerful the library is.

A pattern I'm using (which I'm not sure it's a good idea), is nesting my writes inside my reads (to avoid variable scope issues). Any reason not to do this?

var foo = document.getElementById('foo');
var bar = document.getElementById('bar');

window.addEventListener('scroll', function() {
  fastdom.read(function() {
    var fooHeight = foo.offsetHeight;
    var barHeight = bar.offsetHeight;

    if (fooHeight > barHeight) {
      fastdom.write(function() { bar.style.height = fooHeight + 'px'; })
    }
  });
});

It seems to work without issues for me (no layout thrashing), not sure if theres other perf concerns? This could be a good pattern to include in the README?

i would also be interested in the answer to that question :-)

I added optional support for fastdom to nvd3. There are serious performance benefits to doing so (not as noticeable in chrome, but definitely in IE/FF). https://github.com/nvd3-community/nvd3/pull/8

I have to say that the README / exampls doesn't do a a very thorough job in showing which DOM APIs profit from fastdom, as they only show reading / writing properties on DOM nodes, and not that fastdom can / should also be used when adding or removing elements. Maybe this can be added, too.

[wilsonpage]

@Narretz good point. Would you be able to submit an example(s) to merge?

Just came across this library that I'd like to use in a constraints layout library I'm building, but I'm curious if there are any concerns about nesting calls, similar to what @cobbweb asked? Seems that it could be perf gain to not preform a write if it isn't necessary.

[wilsonpage]

@souporserious nesting calls is perfectly acceptable. You can see in these tests that we have all those cases covered. It's also handy to see the specced behaviour for each case.

Awesome! Thank you for the quick reply 🙏 I read your article, and I'm really stoked to see if I get any perf gains in my layout calculations/rendering.

[wilsonpage]

Sweet! Let me know how it goes 👌
