Pass additional parameters to functions within lodash's flow()

Question

If I want to change the delimiter of join() to something other than the default, how do I pass that to that specific function within this chain?

const evens = (x) => _.filter(x, y => y % 2 === 0)

console.log(
  _.flow(
    evens,
    _.join,
  )([1, 2, 3, 4, 5, 6])
) 
// expected output: ('2+4+6')
// actual output: ('2,4,6')

Answer 1

This works

const evens = (x) => _.filter(x, y => y % 2 === 0)

console.log(
  _.flow(
    evens,
    (a) => _.join(a, '+'),
  )([1, 2, 3, 4, 5, 6])
)
