Please use this thread to discuss Leopard, share your projects, and ask for help.


That's right! Translating Scratch to JavaScript is now possible! The tool is called Leopard, and it's available here:

Leopard Website – Go here to convert your projects!

Who needs this?
If you know Scratch and want to learn JavaScript, Leopard is made for you. It's the perfect transition tool. Leopard also allows you to convert your existing Scratch projects into JavaScript code and edit them that way.

What if it doesn't work?
Not every project will translate perfectly. That's why we have a team of Leopard Mentors who are here to offer support. If you are having trouble with a project, you can ask here on the forums or create a dedicated “cleanup crew” post to get more 1-on-1 help.

Thank you so much to the contributors who made Leopard possible!

I put one of my projects and a problem repeatedly occurred twice
It doesn't work anymore

Hey everyone!

The funding I had available to host the project editor directly on the Leopard website ran out. That means it's time to go back to editing within CodeSandbox or just downloading projects as a zip. The “Leopard Editor” option is being removed.

If you have projects saved on the website, you have a little over a month to download them, copy them, whatever you want to do, before the content on the website will be removed.

BXCoding have been wonderful partners supporting the Leopard website infrastructure at no cost to me during this period of a couple years. If you like Leopard, you should definitely also check out their project Patch which is like Scratch but in Python.

PullJosh, you could use Replit.com to host leopard.js for free. (Only one app can be published at a time when using replit's starter plan.)
also, please fix this thing: cannot read properties of ('undefined')

Can you make the website support more then just pen? I have a OS i want to convert to assembly, (i would use that python code to convert to assembly) but as OSs are, it would be too big and have more then just pen.
