> Why not assign each call to a variable for readability? The problem is that if you use a variable, you either: - use a new variable each time, therefore you have to think of appropriate name each time (and having a lot of variables does not necessarily make code more readable) - or you have to come up with a rather generic name of variable, like "result" or "output", otherwise the name will not make sense until the very end where the last value is assigned Let's say I want to have a list of active products from some category. With option 1 it would be: const allProducts = Product.all() const activeProducts = allProducts.filterActive() const activeHouseProducts = Category.match(activeProducts, "house") with option 2 you'd do: var activeHouseProducts = Product.all() activeHouseProducts = activeHouseProducts.filterActive() activeHouseProducts= Category.match(activeHouseProducts, "house") and with pipe operator you can do: const activeHouseProducts = Product.all().filterActive() |> Category.match(%, "house")
