Hi,

I cannot figure out how to define functions with parameters in [https://makecode.mindstorms.com](https://makecode.mindstorms.com). Not even in the text based _JavaScript_ tab.

Is this impossible or a good reason for this, or is it just a small fix away, since my understanding is that this is supported both in the STS language, core pxt and all other MakeCode editors?

here are no parameters in the function because the stable version of pxt-ev3 has an old editor core. In the beta version, the kernel is new and there are function parameters.

Thanks for your quick reply which was very illuminating and helpful, @THEb0nny!

I was about to ask whether the beta version would ever be published as an updated new stable, but you already answered that here:

> Check out the beta version. It’s included there. But it worked on my computer, and when I tried it on the computer at school, for some reason it didn’t work there, but I haven’t figured it out yet. There are a lot of changes in beta. Most likely the beta will never transition to a stable version, because… the developers no longer support the project themselves.

Don’t this work?

```auto
function myFunc(param1: number, param2: number) {
     return param1 + param2
}

```

Kind of…

It “grey blocks” in the regular edition, but works in JavaScript mode:

But works in beta:
