`Reduce` combine a list of values into a single value. `acc` is the initial state, and each successive step of it should
|
|
be returned by the reduction function.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{0, 1, 2, 3, 4, 5, 6, 7, 8, 9}
|
|
sum := func(n, acc int) int { return n + acc }
|
|
fmt.Println(u.Reduce(nums, sum, 0)) // 45
|
|
}
|
|
```
