`underscore` is a `Go` library providing useful functional programming helpers without extending any built-in objects.
|
|
|
|
It is mostly a port from the `underscore.js` library based on generics brought by `go1.18`.
|
|
|
|
## Quick Start
|
|
|
|
Install the library using
|
|
|
|
```shell
|
|
go get github.com/rjNemo/underscore
|
|
```
|
|
|
|
Please check out the [examples](https://github.com/rjNemo/underscore/tree/main/examples) to see how to use the library.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
numbers := []int{1, 2, 3, 4, 5, 6, 7, 8, 9}
|
|
// filter even numbers from the slice
|
|
evens := u.Filter(numbers, func(n int) bool { return n%2 == 0 })
|
|
// square every number in the slice
|
|
squares := u.Map(evens, func(n int) int { return n * n })
|
|
// reduce to the sum
|
|
res := u.Reduce(squares, func(n, acc int) int { return n + acc }, 0)
|
|
|
|
fmt.Println(res) // 120
|
|
}
|
|
```
