GoDash
Finally! Introduction of Generics in Golang allows implementation of reusable algorithms or functional programming primitives wiht much less hassle.
The project is work in progress: intended to learn and be of practical use.
Please consider performance aspects of Go generics when implementing time-critical systems.
Godash is like Lodash‘s younger cousin.
Makes use of generics in Go, hence requires Go 1.18.
Usage
import "github.com/tomekc/godash"
Functional primitives
Map
Returns slice of elements transformed by mapper function.
var mapper = func(s string) int {
return len(s)
}
result := Map([]string{"alice", "bob", "charlie"}, mapper)
// {5, 3, 7}
Filter
Returns array of items matching given predicate function.
func IsOddInteger(i int) bool {
return i%2 == 1
}
result := godash.Filter([]int{1, 2, 3}, IsOddInteger)
// {1, 3}
ForEach
Execute function on each element of slice.
var urls []string{}
// ...
godash.ForEach(urls, func(url) {
fetch(url)
})
