@richard when did we get the ability to use multiple things for arrays I cannot express my gratitude for this. Cheers makecode team ---

What exactly do you mean? Like put multiple types of items in an array? I thought you could always do that. ---

I thought I caused an error I was dang sure of that when I did nested arrays with different stuff ---

The thing is that you can’t actually _use_ these arrays. For example, if you created an array of a number and some text, it would be of type “string | number” which you can’t really do anything with (in blocks). Unless you are type checking it, which doesn’t exist in blocks, it will cause an error… wait… ok new [pxt-JavaScript-extras](https://forum.makecode.com/t/making-an-extension-for-every-javascript-exclusive-feature-i-can-think-of/36766) update, I’ve added the “typeof” block. You can now do type checking in blocks, have fun. Nope. No fun to be had here. The compiler still complains if you use the block I made, sorry. You would have to go into JavaScript, type “typeof”, and then switch back to make the compiler happy. Very sad. ---

I used number and sprite in a dialog box and it displayed both ---

Yes that makes sense as the dialogue box accepts any input. I thought you were talking about arrays?
