How long are bins kept for?
They’re kept indefinitely. In JS Bin’s early life, back in 2008, we removed them after not being seen for 3 months, but that’s long been removed. Bins are permanent.
When I change the url to a different JS Bin, it still has the old code
Click the revert button and it will reload the code from the database based on the url you requested.
Can I run a Gist in JS Bin?
How does the error checking work?
Error checking is provided by the JSHint project. Like JSLint, but maintained and with a lovely API so I could plug it into JS Bin.
Can I just show the HTML panel?
Yes. Append #html to the end of the url when sending a saved JS Bin and when the link is opened, only the HTML tab will be shown.
How do I re-run or re-render the code
Just click the ‘Preview’ button, and your entire code will re-run.
Can JS Bin respond to Ajax requests?
Yes. See the Ajax debugging video for a demo. Or, it’s as simple as removing the HTML output, saving the code, then requesting the URL via a new snippet. JS Bin will respond to Ajax requests appropriately.
I’m afraid not, but the application is open source, so if you think you can get it working - please go ahead: http://github.com/remy/jsbin
