fp typescript utility function with data first + data last

pnpm i @krist7599555/lodosh

all function can be call in datafirst or datalast to make pipe function able to infer type correctly

func(data, ...args); // data first
func(...args)(data); // data last

example

const out1 = pipe(
  movies,
  sort_by((it) => [
    ["desc", it.rate],
    ["acs", it.name],
  ])
);
const out2 = pipe(
  students,
  group_by_with(
    (it) => it.course,
    (its) => ({
      course_name: its[0].cource,
      average_grade: avg_by(its, (it) => it.grade),
      students: sort_by(its, (it) => [["asc", it.id]]),
      students_boys: arr_filter(its, is_match({ gender: "male" })),
    })
  )
);
