every filter operates on its input. in this case the input was an array. every map implementation ive seen has type function(a,b) -> list(a) -> list(b) select

every filter operates on its input. in this case the input was an array.
every map implementation ive seen has type function(a,b) -> list(a) -> list(b)
select(contains("good/")) is a function from string -> string|void
so map plus a voidable function equals a filter
| just means connect 2 filters
if you have a stream you turn it into a array with the array constructor []
if you have an array you turn it into a stream with the producer operator .[]
the api is super orthogonal and well designed. but you do have to understand the model
- throwaway894345 5y agoRight, I already believe it all makes sense when you understand the model, but the model isn't super obvious and I often find myself Googling things for reference because I don't use it very often; however, I do use regular programming languages and I can reason about those more easily (although while I like Go, I would be more inclined to used a Python- or JS-like language for something like this).
