`Last` returns the last element of the slice. Panics if the slice is empty with a clear error message.
|
|
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"fmt"
|
|
u "github.com/rjNemo/underscore"
|
|
)
|
|
|
|
func main() {
|
|
nums := []int{1, 9, 2, 8, 3, 7, 4, 6, 5}
|
|
fmt.Println(u.Last(nums)) // 5
|
|
|
|
// Single element
|
|
single := []int{42}
|
|
fmt.Println(u.Last(single)) // 42
|
|
|
|
// Empty slice panics with clear message
|
|
// empty := []int{}
|
|
// u.Last(empty) // panic: underscore.Last: empty slice
|
|
}
|
|
```
