Discussion on: Lodash chaining alternative

I think the point of flow is that it defines a proper functional pipeline as a callable, that you will call later with the data. In functional programming, the data is normally last and the flow itself is also chainable and can be included inside a wider functional pipe. Chaining is the other way around. I'd argue that flow in the order it is presented by lodash is perfectly correct and makes total logical sense if you use it to define the function:

const processInputData = flow(
  map(x => [x, x*2]),
  flatten,
  sortBy(x => x) 
)

processInputData([1,2,3])
processInputData([4,5,6])

const complexProcess = flow(
   processInputData,
   map(([a,b])=>[a,b,a*b,a+b])
)

complexProcess([7,8,9])
