f
f is a simple library that leverages the new generics in Golang to create a tools for functional style of code.
Pipe
like '|>' in Elixir or Elm.
input := 1
add1 := func(i int) int { return i + 1 }
mul2 := func(i int) int { return i * 2 }
f.Pipe(input, add1, mul2) // 4
Collections
Map
f.Map(func(elem int) int { return elem * 2 }, []int{2, 3, 4, 5}) // [4, 6, 8, 10]
Reduce
f.Reduce(0, func(a, b int) int { return a + b }, []int{1, 2, 3, 4, 5, 6}) // 21
Filter
f.Filter(func(elem int) bool { return elem%2 == 0 }, []int{1, 2, 3, 4, 5, 6}) // [2, 4, 6]
Nth
f.Nth([]int{1, 2, 3, 4, 5}, 2) // 3
Take
f.Take([]int{1, 2, 3, 4, 5}, 2)) // [1, 2]
TakeLast
f.TakeLast([]int{1, 2, 3, 4, 5}, 2)) // [4, 5]
Remove
f.Remove([]int{3, 4, 5}, 0)) // [4, 5]
Head
f.Head([]int{3, 4, 5})) // 3
Tail
f.Tail([]int{3, 4, 5})) // [4, 5]
