First one:jsfiddle
Very powerful JS online debugging tools, support a variety of application of a variety of mainstream framework, can be directly edited online editing: HTML, CSS, JavaScript, easy to use, but also can debug the results of a very concise page directly embedded in other pages, So I need to write a demo of JavaScript instance code, you can completely in Jsfiddle directly after debugging, and then directly embedded in the blog text can be, really is very convenient choice, as shown below ( This example can only see the result in Firefox).
Second: js Bin
."
Both of these tools were just born soon, are still in continuous improvement, although the current jsfiddle to better than JS bin, but I still more optimistic about the latter, JS bin author in GitHub's project homepage, said the first version of the development he only spent 4 hours, really strong ah, The second version that is being developed he will be completely reconstructed, will soon be released, very much looking forward to.
