`Each` iterates over a slice of elements, yielding each in turn to an action function.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
names := []string{"Alice", "Bob", "Charles"}
|
|
res := make([]string, 0)
|
|
|
|
u.Each(names, func(n string) {
|
|
res = append(res, fmt.Sprintf("Hi %s", n))
|
|
})
|
|
fmt.Println(res) // {"Hi Alice", "Hi Bob", "Hi Charles"}
|
|
}
|
|
```
