Should be used sync function in when ?

[love8587]

I'm trying rules engine to implement evaludate articles to accept automatically.

I researched rules enginer and rools module looks good for me.

However, there is a part that has been hesitating.

I think when conditions could be async functions. Is it should be compose of sync functions ?

yes, premises (when) are always working synchronously on the facts.

Thanks for your answer. Can I get a some refference to understand the reason why Promises are always working synchronously ?

Thanks for the question. The answer is probably for performance reasons and because I was thinking that it is not required. But why not. Let me think about it.
