FP Go

A light-weight FP utils for Go

Usage

All functions are group by the data type they are processing, for example we can slices.Map a function to a slice

import "github.com/jcouyang/fp.go/slices"

strLen := func (a1 string) int {
	return len(a1)
}

fmt.Println(
	slices.Map(strLen)([]string{"cat", "catfish", "caterpillar"}),
)
// Output: [3 7 11]

Similarily, we can also Map the function to a chan with chans.Map

import "github.com/jcouyang/fp.go/chans"

wordChan := make(chan string, 3)
wordLenChan := chans.Map(strLen)(wordChan)

wordChan <- "cat"
wordChan <- "catfish"
wordChan <- "caterpillar"
	
fmt.Println(
	<-wordLenChan,
	<-wordLenChan,
	<-wordLenChan,
)
// Output: 3 7 11
