Hi @HarelM First of all, big thanks for your effort!
I opened the PR by mistake because I wanted to test the changes in my fork first but once open I'll keep working on this one.

It would be great to let us know what are you solving.

We are moving from mapbox-gl and I found some definition errors on our existing expressions so I thought I could collaborate updating their types definition (thanks again for moving to typescript! 🙇 )

This was the error:

Writing expressions has been always difficult for me, so typing them are even harder but I think we can have a generic solution to allow writing any kind of expression. And that is why I added a list of every filter available in the documentation

Note that you are editing a generated file. Please make sure to fix the code generation.

I thought the src/style-spec/types.ts is a source type definition file, could you explain then a bit more how that works ?

Also it would be great if you can check the relevant tick boxes in this template.

Sure, let me accommodate and understand all and will keep you updated once they are ready

If there's an issue you are solving with the PR, even better.

I haven't found any, but If that is the workflow I can create one explaining the error and point it here
