// Flow is a construct that can chain together functions.
// Flow denotes regular function composition.
var chain1 = 
 Flow <- f1
      <- f2
      <- f3

chain1(123) // same as f3(f2(f1(123)))

// Can also chain together multiple things that go to one.
var chain2 =
 Flow <- f1 & f2 
      <- f3

chain2(123) // same as f3(f1(123), f2(123))

//Now the interesting part is what if you don't want functions brought together in this way?
//Say you want f3([f1(123), f2(123)]) to output as an array instead of separate args.
//Just define a new flow construct

var chain3 =
FlowArr <- f1 & f2
        <- f3

chain3(123)
// same as f3([f1(123), f3(123)])

//Since each part acts on functions and returns a function, you can comprise more than one type together.
var chain4 = 
Flow
  <- f1 & f2
  <- f3
  (FlowArr
    <- f4 & f5
    <- f6)

chain4(123)
//same as 
// var temp = f3(f1(123), f2(123))
// f6([f4(temp), f5(temp)])
