is it just me or is the ‘edit as javascript’ option down for everyone?

It works for me (with the default project).

Ah this leopard program is Great! coz now i can start with Jvs coz you put in scratch to Jvs translations and a Jvs editor!
Thanks so much coz now am gonna start learning Jvs and when i make a good game or something on it i'll send you a link!

Thanks: AppelAnimator

How do you import a project from the js to scratch?

Good question! Unfortunately, JS to Scratch is not possible with Leopard. Only Scratch to JS.

(Also, please don't repost the same thing multiple times. Thanks. ;))

Hi, I seem to be having an issue, I can't even get on to the page it's self.
And, yes, I did test other mods, it's just this one.
(I went to Turbowarp and Phosphorous, Snap)

Why is there a “*” at the beginning of a procedure name and after the keyword “Yield” ?
I didn't find that in the documentation.

It's a little detail surrounding generator functions. You can learn about it here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/yield*

Some of the built-in Leopard methods (especially the blocks that take a long time to run) are generators, and in those cases you have to use yield*. If you just copy what the translator does, you should be all good.

So it's basically Python's yield from?

Yep. yeild* = yeild from, yeild = yeild - but yeild* can only be used to yeild generator functions, not to loop and yeild an array or something of the sort.

Thanks to all these good people who answered my question .. but only in part.
Here is the second part with more details.
In the source code generated by Leopard
(which I find marvellous despite the fact that I didn't yet take a look at its script, but I will for sure)
procedures (or methods) are defined this way :

*procedureName (param, param…) {
statement;
statement;
statement
}
As I can see, there is a “ * ” before the name of the procedure, despite the fact
that in my Scratch script my procedure doesn't start with such a “ * ”.
I'm not criticising nor am I pointing to any bug. I am curious as much as you are,
R.L.

Procedures that start with “*” are generator functions, that use yeild or yeild* rather than return to return values, and they use return to stop the genetator. These can be used as“ for (i in procedure()) …” or as “procedure.next()”. Read more at https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/function*
The reason these are needed is because of tge way scratch's threading works; there's a good explanation at https://github.com/TurboWarp/scratch-vm#javascript-generation - some of it's specific to turbowarp, but a lot is very relevant to leopard.

Au contraire,

function * owo () {
  yield 'uwu'
  yield * [1, 2, 3, 4]
}
[...owo()] // -> ["uwu", 1, 2, 3, 4]

Any iterator or iterable (including arrays) can be yield *'d
