`Init` returns all elements except the last one, and the last element separately. Returns an empty slice and zero value if the input slice is empty. Useful for destructuring lists from the right.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 2, 3, 4, 5}
|
|
init, last := u.Init(nums)
|
|
fmt.Println(init) // [1, 2, 3, 4]
|
|
fmt.Println(last) // 5
|
|
|
|
// Single element
|
|
single, val := u.Init([]int{42})
|
|
fmt.Println(single) // []
|
|
fmt.Println(val) // 42
|
|
|
|
// Empty slice
|
|
empty, zero := u.Init([]int{})
|
|
fmt.Println(empty) // []
|
|
fmt.Println(zero) // 0
|
|
}
|
|
```
